Dirac operator on κ-Minkowski space bicovariant differential calculus and deformed U(1) gauge theory
P. N. Bibikov
Abstract
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.
