C (1) n , D (1) n and A (2) 2n−1 reflection K-matrices
Abstract
We investigate the possible regular solutions of the boundary Yang-Baxter equation for the vertex models associated with the
C
(1)
n
,
D
(1)
n
and
A
(2)
2n−1
affine Lie algebras. We find three types of solutions with
n
,
n−1
and 1 free parameters,respectively. Special cases and all diagonal solutions are presented separately.
