On the structure of the constraint algebra for systems whose gauge transformations depend on higher order time derivatives of the gauge parameters

Abstract

The dynamical systems invariant under gauge transformations with higher order time derivatives of the gauge parameter are considered from the Hamiltonian point of view. We investigate the consequences of the basic requirements that the constraints on the one hand and the Hamiltonian and constraints on the other hand form two closed algebras. It is demonstrated that these simple algebraic requirements lead to rigid relations in the constraint algebra.
