Yang-baxter Equation And Quantum Enveloping Algebras

The exact solution of C N Yang''s one-dimensional many-body problem with repulsive delta-function interactions and R J Baxter''s eight-vertex statistical model are brilliant achievements in many-body statistical physics. A nonlinear equation, now known as the Yang-Baxter equation, is the key to the solution of both problems. The Yang-Baxter equation has also come to play an important role in such ...
