Canonical and Lie-algebraic twist deformations of $κ$-Poincare and contractions to $κ$-Galilei algebras
Abstract
Description
We propose canonical and Lie-algebraic twist deformations of $κ$-deformed Poincare Hopf algebra which leads to the generalized $κ$-Minkowski space-time relations. The corresponding deformed $κ$-Poincare quantum groups are also calculated. Finally, we perform the nonrelativistic contraction limit to the corresponding twisted Galilean algebras and dual Galilean quantum groups.
