Description
In 1992, Shibukawa and Ueno derived a family of solutions to the
Yang-Baxter equation as operators on function space. In this framework,
we study the connection between well-known elliptic solutions and
trigonometric degenerations, and construct a new family of rational
solutions, which generalize to higher dimensions the Jordanian R-matrices.
These solutions are obtained from twisted Shibukawa-Ueno operators
restricted to finite dimensional subspaces, and the trigonometric and
rational degenerations are described via these function spaces.
