Realizations of Galilei algebras
(Institute of Physics Publishing, 2016)
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 ...
Differential Invariants and Realizations of the Deformed Smallest Galilei Algebra
(MAIK "Nauka/Interperiodica", 2018)
Deformations of the smallest Galilei algebra are constructed and deformed algebras are realized by Lie vector fields. For these realization bases of differential invariants and operators of invariant differentiation are ...
