Realizations of Galilei algebras
Abstract:
All inequivalent realizations of the Galilei algebras of dimensions not
greater than five are constructed using the algebraic approach proposed by
Shirokov. The varieties of the deformed Galilei algebras are discussed and
families of one-parametric deformations are presented in explicit form. It
is also shown that a number of well-known and physically interesting
equations and systems are invariant with respect to the considered Galilei
algebras or their deformations.
