A Conjecture for the Effecture Condition of Jimbo's Method

  • The method for constructing the spectrum-dependent solutions to the Yang-Baxter equation,according to Jimbo's theorem,is based on the existence of the representation matrix of e0,corresponding to the lowest negative root,in an irreducible representation of a quantum eveloping algebra.In this paper a conjecture for the existent condition of the representation matrix of e0 is made.As an example,the adjoint representation of Uq C2 is discussed where the representation matrix e0 does not exist because the existent condition is violated.

Abstract: The method for constructing the spectrum-dependent solutions to the Yang-Baxter equation,according to Jimbo's theorem,is based on the existence of the representation matrix of e0,corresponding to the lowest negative root,in an irreducible representation of a quantum eveloping algebra.In this paper a conjecture for the existent condition of the representation matrix of e0 is made.As an example,the adjoint representation of Uq C2 is discussed where the representation matrix e0 does not exist because the existent condition is violated.
