Canonical and Lie-algebraic twist deformations of $κ$-Poincare and contractions to $κ$-Galilei algebras

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/222879We 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.16 pages, no figures, v3: few changes provided - version for journal, v2: submitted incidentally, v4: the page numbers for all references in preprint version are providedMathematical PhysicsHigh Energy Physics - TheoryCanonical and Lie-algebraic twist deformations of $κ$-Poincare and contractions to $κ$-Galilei algebrastext
