40 Years in Mathematical Physics

This is a collection of Prof L D Faddeev's important lectures, papers, and talks. Some of these have not been published before and some have, for the first time, been translated from Russian into English. The topics covered include Prof Faddeev's contributions to the modern mathematical quantization of Yang–Mills and Einstein gravitational fields, soliton theory, the many-dimensional inverse problem in potential scattering, the Hamiltonian approach to anomalies, and the theory of quantum integrable models. It also contains two papers on the broader interrelations between physics and mathematics as well as an autobiographical essay.
