On κdeformation and triangular quasibialgebra structure
Abstract
We show that, up to terms of order κ, the κdeformed Poincaré algebra can be endowed with a triangular quasibialgebra structure. The universal R matrix and coassociator are given explicitly to the first few orders. In the context of κdeformed quantum field theory, we argue that this structure, assuming it exists to all orders, ensures that states of any number of identical particles, in any representation, can be defined in a κcovariant fashion.
