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 e ₀,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 e ₀is made.As an example,the adjoint representation of U _qC ₂is discussed where the representation matrix e ₀does not exist because the existent condition is violated.
