2.1. Curved area of λm,n-vacuum
Let’s consider a curved area of vacuum. If the wavelength
λm,n of test monochromatic light rays is much smaller than the dimensions of the vacuum curvature, then in this area the cubic cell of the
λm,n-vacuum (i.e., the cubic cell of the 3D
m,n-landscape, which limited by these rays) will be curved (see
Figure 4a).

We consider one of the eight vertices of the curved cube of the
λm,n-vacuum (see
Figure 4a). Let’s replace the distorted edges emerging from this vertex with distorted axes of the curvilinear coordinate system
x′
0(а),
x′
1(а),
x′
2(а),
x3′
(а) (see
Figure 4b). We denote the same edges of the original, ideal cube by the pseudo-Cartesian coordinate system
x0(а),
x1(а),
x2(а),
x3(а).
In the area of the vertex of the angle under consideration (see
Figure 4b), its distortions can be decomposed into two components: 1) changing the lengths (compression or expansion) of the axes
x′
0(а),
x′
1(а),
x′
2(а),
x3′
(а) while maintaining right angles between these axes; 2) deviations of the angles between the axes
x′
0(а),
x′
1(а),
x′
2(а),
x′
3(а) from right angles (i.e., 90
o) while preserving their lengths.
Let's consider these distortions separately.
1) Let only the lengths of the axes
x′
0(а),
x′
1(а),
x′
2(а),
x3′
(а) change near the vertex during the curvature, then these axes can be expressed through the original (ideal) axes
x0(а),
x1(а),
x2(а),
x3(а) using the corresponding coordinate transformations [
3]:
where
is the Jacobian of the transformation, or the components of the elongation tensor.
2) Now let the distortion near the vertex be associated only with a change in the angles between the axes of the coordinate system x′0(а), x′1(а), x′2(а), x3′(а), while the lengths of these axes remain unchanged. In this case, it is sufficient to consider only the change in the angles between the basis vectors e′0(a), e′1(a), e′2(a), e′3(a) of the distorted reference system.
It is known from vector analysis that the basis vectors of the distorted 4-basis
e′
0(a),
e′
1(a),
e′
2(a),
e′
3(a) can be expressed in terms of the original basis vectors
e0(a),
e1(a),
e2(a),
e3(a) of an orthogonal 4-basis by means of the following system of the linear equations [
3]:
where
are the guiding cosines.
The systems of Eqs. (1) and (3) can be represented in a compact form:
here and below, the “Einstein summation rule” is used.
For example, we write the vector (48) in [
1]
in the distorted 4-basis, taking into account Exs. (5) and (6), vector (7) can be represented as
Distortions of the remaining 7 trihedral angles of the curved cube of the
λm,n-vacuum (
Figure 4) (i.e., the fifteen remaining 4-bases shown in
Figure 5, or
Figure 7 in [
1]) are described in a similar way.
Thus, all sixteen 4-bases (see
Figure 5) associated with the distorted trihedral angles of the
λm,n-vacuum cube (see
Figure 4) can be represented by the vectors
where
а = 1,2,…,16.
2.3. The first stage of compactification of curved measurements
Just as it was done in §2.3 in [
2], at the first stage of the compactification of additional curved mathematical dimensions in the Algebra of Signatures, metric 4-spaces with the same signature are averaged.
For example, for metrics with signature (– + – +), we have the following averaged metric tensor
where
p corresponds to the 14-th signature (– + – +), according to the following conditional numbering of signatures:
This matrix with numbered signatures corresponds to the matrix of signatures (32) in [
2].
As a result of operation (21), the averaged metric is obtained
Similarly, as a result of averaging type (21) – (23) out of 256 metrics (18) of curved metric 4-spaces, we can obtain 256 : 16 = 16 averaged metrics with 16 possible signatures
where ‹ › means averaging.
If the additive superposition (i.e., summation) of all these 16 averaged metrics (24) is equal to zero
then this expression can be used for an average flat
λm,n-vacuum. At the same time, it is a condition for maintaining the
λm,n-vacuum balance.
Recall that the “vacuum balance condition” was formulated in the introduction of the article [1], and this is the basic statement that, in particular, no matter what convex-concave curvatures (fluctuations) occur with the local area of the λm,n-vacuum, on average over the entire area they are equal to zero.
In this case, all 16×16=256 components of 16 averaged metric tensors сij(p) can be random functions of time. But, according to the condition of λm,n-vacuum balance, these metric-dynamic fluctuations should overflow into each other so that the total metric (25) on average remains equal to zero.
Based on the metric (25), λm,n-vacuum thermodynamics can be developed, which considers the most complex, near-zero “transfusions” of the local λm,n-vacuum curvatures. Concepts about λm,n-vacuum entropy and temperature (i.e., the essence of chaoticity and intensity of local λm,n-vacuum fluctuations) can be introduced. We can talk about the “cooling” of the λm,n-vacuum to “freezing”, its “heating” to “evaporation” and many other effects similar to the processes occurring in atomistic continuous media.
Features of
λm,n-vacuum thermodynamics are associated with processes when the gradients of
λm,n-vacuum fluctuations approach the speed of light (
dсij(p)/dxa ~ c) or zero (
dсij(p)/dxa ~ 0). A detailed consideration of
λm,n-vacuum thermodynamics and torsion fields is beyond the scope of this article. However, some aspects of this area of research are considered in [
3,
4,
5].
2.4. The second stage of compactification of curved mathematical measurements
Just as it was done in §7.2 in [
2], Ex. (25) can be reduced to two terms
is the quadratic form, which is the result of averaging seven metrics from the list (24) with signatures included in the numerator of the left rank (43) in [
2] or (29);
is the quadratic form, which is the result of averaging seven averaged metrics from the list (24) with signatures included in the numerator of the right rank (43) in [
2] or (29).
Thus, from the complex λm,n-vacuum fluctuations, two averaged sides can be distinguished:
1) the averaged “outer” side of the 2
3-λm,n-vacuum (or
subcont, see §2.7 in [
2]) with the averaged metric
here
are components of the metric tensor of the
subcont (i.e., the “outer” side of the 2
3-λm,n-vacuum).
2) the averaged “inner” side of the 2
3-λm,n-vacuum (or
antisubcont, see §2.7 in [
2]) with the averaged metric
here
are the components of the metric tensor of the
antisubcont (i.e., the “inner” side of the 2
3-λm,n-vacuum).
Recall that the two-sided model of λm,n-vacuum, that is, the result of averaging complex metric-dynamic fluctuations of λm,n-vacuum to a two-sided level of consideration, is called in §2.7 in [2] “23- λm,n-vacuum”, because in this case, only 4 + 4 = 8 = 23 mathematical measurements remain within the framework of consideration.
To shorten the notation, the averaging signs < > of the components of the metric tensors (32) and (35) are omitted.
Once again, we note that two concepts were formally introduced in [
1]:
- subcont (i.e., the substantial continuum or the outer side of the 23-λm,n-vacuum with the averaged metric (30) and with the signature (+ – – –) of the Minkowski space);
- antisubcont (i.e., antisubstantial continuum or inner side of 23-λm,n-vacuum with averaged metric (33) and signature (– + + +) of Minkowski antispace).
The fictitious concepts of subcont and antisubcont are introduced to simplify and facilitate our perception of the complex intra-vacuum processes.
Thus, from the complexly fluctuating
λm,n-vacuum (see
Figure 6), due to simplification and averaging, we singled out only one averaged 2
3-λm,n-vacuum with two mutually opposite 4-dimensional sides:
subcont and
antisubcont (see
Figure 7).
On
Figure 7 conditionally shows the average section of the two-sided 2
3-λm,n-vacuum, the outer side of which (
subcont) is described by the averaged metric
(30), and the inner side (
antisubcont) is described by the averaged metric
(33).

Let’s explain the importance of at least two-sided consideration with a simple example. Let's take a sheet of paper and draw lines (segments) of the same length on its two sides in the same place (see
Figure 8 a,b)
Reference systems ХУ or Х′У′ on two opposite sides of a sheet of paper have different stignatures, respectively {+ +} and {+ –}. To understand this, take a sheet of paper and draw on it the XY reference system (as in Figure 8a). Then turn the sheet over, and on its reverse side depict the Х′У′ reference system in the same way in the same place. If you compare these reference systems, you will find that the X and X′ axes are directed in different directions, so their stignatures are different.
If the given sheet of paper is not curved, then the reference system with stignatures {+ +} and {+ –} are alike, i.e., any of them can set the coordinates of the drawn lines.
However, if this sheet is bent (see
Figure 8c), then the line on the outer side of the sheet (see
Figure 8a) will slightly expand, and the line on the inner side of the sheet (
Figure 8b) will shrink by almost the same amount. In other words, the expansion of one line inevitably leads to the compression of another line drawn on the opposite side of the sheet.
Therefore, at least a two-sided consideration of the process of curvature of a sheet of paper is inevitable. Otherwise, one-sided consideration will lead not only to the loss of information about the process under study, but also in some cases to paradoxical and erroneous conclusions. In addition, the two-pronged approach immediately takes into account the vacuum balance condition, which states that any action is accompanied by a reaction. In the considered case, the expansion of one line is inevitably accompanied by compression of the other line, therefore, if we neglect the thickness of the sheet, then its average deformation of these lines tends to zero.
In fact, a sheet of paper has a thickness
ε (see
Figure 7). Therefore, in its thickness, one can always distinguish a cube with an edge length
ε (see
Figure 7 and
Figure 9).
If the sheet is bent, all sixteen 3-bases associated with the trihedral angles of such a deformed cube will be distorted in different ways (see
Figure 4). Therefore, the Algebra of Signatures develops a mathematical apparatus that initially takes into account the distortions of all sixteen 3-bases at once, shown in
Figure 9.
Only in the case when the thickness of a sheet of paper is so small that it can be neglected, it is permissible to simplify the problem to a two-sided consideration.
Unilateral consideration, i.e. the study of the curvature of only one side of a sheet of paper is possible, but will inevitably lead to a fundamental incompleteness of the mathematical model of the process under study.
In relation to vacuum physics, we are forced to state that the void (i.e., vacuum), which plays the role of the space surrounding us, has at least two sides: 1) external, i.e. Minkowski space with signature (+ – – –) and 2) internal, i.e. Minkowski antispace with signature (– + + +) (see
Figure 7). One-sided consideration will inevitably lead to dead-ends and unfinished areas of scientific research.
For example, a metric that is a solution to the equations of the general theory of relativity (GR) of A. Einstein with the signature (+ – – –) can only describe a one-sided cosmological model of the Universe, which, in principle, cannot be completed. We also need, at a minimum, a metric-solution of the same equations with the opposite signature (– + + +). A more complete cosmological model should take into account all 16 metric-solutions of GR equations with signatures (29). Only such a cosmological model can claim logical completeness. The project of the cosmological model taking into account metric-solutions with all 16 possible signatures will be presented in subsequent articles of this project.
