Variational problems without having any non-trivial Lie variational symmetries

Abstract

In this paper we construct variational problems without Lie non-trivial variational symmetry and solving them using new class of symmetries ($\mu$-symmetry) which introduced by Guiseppe Gaeta and Paola Morando (2004). The central object in this paper is horizontal one-form $\mu$ on first order jet space $J^{1}M$.
