This volume contains the proceedings of the conference on Advances
in Quantum Dynamics. The purpose of the conference was to assess the
current state of knowledge and to outline future research directions of quantum
dynamical semigroups on von Neumann algebras.

Since the appearance of the landmark papers by F. Murray and J. von Neumann,
On the Rings of Operators, von Neumann algebras have been used as a
mathematical model in the study of time evolution of quantum mechanical
systems. Following the work of M. H. Stone, von Neumann, and others on the
structure of one-parameter groups of unitary transformations, many researchers
have made fundamental contributions to the understanding of time-reversible
dynamical systems. This book deals with the mathematics of time-irreversible
systems, also called dissipative systems. The time parameter is the half-line,
and the transformations are now endomorphisms as opposed to automorphisms.

For over a decade, W. B. Arveson and R. T. Powers have pioneered the effort
to understand the structure of irreversible quantum dynamical systems on von
Neumann algebras. Their papers in this volume serve as an excellent
introduction to the theory. Also included are contributions in other areas
which have had an impact on the theory, such as Brownian motion, dilation
theory, quantum probability, and free probability.

The volume is suitable for graduate students and research mathematicians
interested in the dynamics of quantum systems and corresponding topics in the
theory of operator algebras.
