Abstract

We define a family of representations {ρn}n0\{\rho_n\}_{n\geq 0} of a pure braid group P2kP_{2k}. These representations are obtained from an action of P2kP_{2k} on a certain type of A2A_2 web space with color nn. The A2A_2 web space is a generalization of the Kauffman bracket skein module of a disk with marked points on its boundary. We also introduce a triangle-free basis of such an A2A_2 web space and calculate matrix representations of ρn\rho_n about the standard generators of P2kP_{2k}.
