The necessary conditions for minimizers of a kind of nonlinear functions
Dan-Yu Yang · 2006
This paper is devoted to the study for the minimizers of a kind of nonlinear functions.This kind of functions is the limit of one-dimensional Ginzburg-Landau model of superconductivity with normal impurity inclusion as the Ginzburg-Landau parameter tends to infinity.The functions have more than one critical points according to various conditions of related parameters.We obtain the necessary conditions for the minimizer of the functions.
