Generic triangular solutions of the reflection equation: $U_q(\widehat{s{l}_2})$ case

Abstract

We consider intertwining relations of the triangular $q$-Onsager algebra, and obtain generic triangular boundary $K$-operators in terms of the Borel subalgebras of $U_q(s{l}_2)$. These $K$-operators solve the reflection equation.
