Vacuum stability and the Cholesky decomposition

arXiv:1102.2896 · doi:10.1140/epjc/s10052-011-1663-9

Abstract

We discuss how the Cholesky decomposition may be used to ascertain whether a critical point of the field theory scalar potential provides a stable vacuum configuration. We then use this method to derive the stability conditions in a specific example.
