A Conjecture for the Applicability Condition of Jimbo's Method
- Received Date: 1991-08-17
Abstract: According to Jimbo's theorem, the method for constructing the spectrum-dependent solutions to the Yang-Baxter equation is based on the existence of the representation matrix of e0 that corresponds to the lowest negative root, in an irreducible representation of a quantum enveloping algebra. This paper discusses a conjecture for the existence condition of the representation matrix of e0. As an example, the adjoin representation of UqC2 is discussed where the representation matrix e0 does not exist because the existence condition is violated.
