Analysis of PDEs 2025-11-20 v1

Abstract

In this paper we consider an SU(2)SU(2) Yang-Mills field propagating in the 4+14+1 dimensional wormhole spacetime. Assuming the spherically symmetric magnetic ansatz the problem reduces to a one dimensional non linear wave equation. This equation posses a degree one solution (instanton) which is odd in space. We consider small, odd perturbations of the instanton and show that it is conditionally asymptotically stable in the odd energy space.
