WebSep 17, 2008 · New integral identities satisfied by topological solitons in a range of classical field theories are presented. They are derived by considering independent length rescalings in orthogonal directions, or equivalently, from the conservation of the stress tensor. These identities are refinements of Derrick's theorem. WebJun 4, 2024 · Derrick’s theorem [1] constitutes one of the most im-portant results on localised solutions of the Klein-Gordon in Minkowski spacetime. The theorem was developed originally as an attempt to build a model for non point-like elementary particles [2, 3] based on the now well known concept of “quasi-particle”.
