On Duality Principles and Related Convex Dual Formulations Through a D.C. Approach for Non-Convex Optimization, Some Corrections and One More New Dual Formulation
Fabio Botelho, Fabio Botelho · 2025
This article develops duality principles and respective convex dual formulations through a D.C. approach applicable to some originally non-convex primal variational formulations. More specifically, in a first step, we develop applications to a Ginzburg-Landau type equation. The results are obtained through basic tools of functional analysis, calculus of variations, duality and optimization theory in infinite dimensional spaces. It is worth emphasizing we have obtained a convex dual variational formulation suitable for a large class of similar models in the calculus of variations.
