Canonical, Lie-algebraic and quadratic twist deformations of Galilei group
Abstract
Description
New Galilei quantum groups dual to the Hopf algebras proposed in [1] are obtained by the nonrelativistic contraction procedures. The corresponding Lie-algebraic and quadratic quantum space-times are identified with the translation sectors of considered algebras.
