Index Theorem for Domain Walls
arXiv:2008.02058 · doi:10.1088/1751-8121/abdd78
Abstract
The paper is devoted to the discussion of index theorem for domain walls condition. We give an extension of the theorem to the case, when not only Yang-Mills connection components have a jump on some surface of co-dimension 1, but also components of a Riemannian connection, while a metric remains continuous.
