On the existence of finite-energy lumps in classic field theories
arXiv:hep-th/0303195 · doi:10.1103/PhysRevD.68.105015
Abstract
We show how the existence of non-trivial finite-energy time-dependent classical lumps is restricted by a generalized virial theorem. For simple model Lagrangians, bounds on energies follow.
