Dirac operator on $κ$-Minkowski space bicovariant differential calculus and deformed U(1) gauge theory
Abstract
Description
Derivation of $κ$-Poincare bicovariant commutation relations between coordinates and 1-forms on $κ$-Minkowski space is given using Dirac operator and Allain Connes formula. The deformed U(1) gauge theory and appearance of an additional spin 0 gauge field is discussed.
