TL;DR

This paper proves the stability and non-degeneracy of a family of entire solutions to the $U(1)$-Yang-Mills-Higgs equations in four-dimensional Euclidean space, confirming a conjecture and providing new examples of stable critical points.

Contribution

It establishes the stability and non-degeneracy of a previously conjectured family of solutions, the first such examples in higher dimensions for this model.

Findings

The solutions are stable critical points of the $U(1)$-Yang-Mills-Higgs functional.

The solutions are non-degenerate.

The proof involves spectral analysis of the linearized operators.

Abstract

We give a positive answer to the conjecture of Liu-Ma-Wei-Wu in \cite{LMWW} that the family of entire solutions to the $U(1)$-Yang-Mills-Higgs equation constructed by the gluing method in that paper are stable. This is the first family of examples of nontrivial stable critical points to the $U(1)$-Yang-Mills-Higgs model in higher dimensional Euclidean space. Intuitively, the stability of these solutions corresponds to the fact that holomorphic curves are area-minimizing. We also show that these entire solutions are non-degenerate. Our proof is based on detailed analysis of the linearized operators around this family and the spectrum estimates of the Jacobi operator by Arezzo-Pacard \cite{ArePac}.
