A note on the non-diagonal K-matrices for the trigonometric A(1)n-1 vertex model
Abstract
This note presents explicit matrix expressions of a class of recently-discovered non-diagonal K-matrices for the trigonometric A(1)n-1 vertex model. From these explicit expressions, it is easily seen that in addition to a discrete (positive integer) parameter l, 1≤ l≤ n, the K-matrices contain n+1 (or n) continuous free boundary parameters.
