# EMS Tracts in Mathematics

This series includes advanced texts and monographs covering all fields in pure and applied mathematics. The Tracts will give a reliable introduction and reference to special fields of current research. The books in the series will in most cases be authored monographs, although edited volumes may be published if appropriate. They are addressed to graduate students seeking access to research topics as well as to the experts in the field working at the frontier of research.

Edited by Michael Farber (Queen Mary University), Michael Röckner (Universität Bielefeld and Purdue University) and Alexander Varchenko (University of North Carolina at Chapel Hill)
