Course description:
The purpose of these lectures is to explain the role of
the classical and quantum Yang-Baxter equations in the
theory of integrable systems and to give an introduction
to some of the relevant mathematical structures.
Topics discussed: Liouville integrability. Lax equations
and zero curvature equations. Double Lie algebras, Lie
bialgebras and Poisson-Lie groups. Yang-Baxter (RTT=TTR)
algebras from the quantization of quadratic Poisson bracket
algebras. Applications illustrated e.g. with Toda lattices,
the non-linear Schroedinger equation and solvable vertex
models of statistical mechanics.
