The κ-Poincaré Group on a C*-level

الأصل · EN

The C*-algebraic κ-Poincaré Group is constructed. The construction uses groupoid algebras of differential groupoids associated to Lie group decomposition. It turns out the underlying C*-algebra is the same as for "κ-Euclidean Group" but a comultiplication is twisted by some unitary multiplier. Generators and commutation relations among them are presented.
