Deformation of Lie derivative and mu-symmetries / P. Morando. - In: JOURNAL OF PHYSICS. A, MATHEMATICAL AND THEORETICAL. - ISSN 1751-8113. - 40:38(2007), pp. 11547-11559.
Abstract:
We introduce, in the spirit of Witten''s
gauging of exterior differential, a deformed Lie derivative that
allows a geometrical interpretation of lambda and mu-symmetries
in complete analogy with standard symmetries. The case of
variational symmetries (both for ODEs and for PDEs) is also
considered in this approach, leading to lambda and
mu-conservation laws.
