Abstract

This article develops duality principles and related convex dual formulations suitable for the local optimization of non-convex primal formulations for a large class of models in physics and engineering. The results are based on standard tools of functional analysis, calculus of variations and duality theory. In particular, we develop applications to a Ginzburg-Landau type equation.

Keywords

convex dual variational formulation; duality principle for non-convex local primal optimization; Ginzburg-Landau type equation

Comment: Dear Sir Editor

We have found an error in the last duality principle for global optimization.

Corrections have been implemented so that the new result is also of local nature.
