PDEs reduction and lambda-symmetries / G. Gaeta, P. Morando. - In: NOTE DI MATEMATICA. - ISSN 1123-2536. - 23:2(2004), pp. 33-73.
Abstract:
So called lambda-symmetries were introduced by Muriel and Romero, and geometrically
characterized by Pucci and Saccomandi [8, 12], in the ODE case. We extend them to
the PDE framework. In this context the central object is a horizontal one-form mu, and we
speak of mu-prolongations of vector fields and mu-symmetries of PDEs. The latter are as good
as standard symmetries in providing symmetry reduction of PDEs (or systems thereof) and
explicit invariant solutions.
