EMS Tracts in Mathematics
Published by the European Mathematical Society (EMS), this series includes advanced texts and monographs covering all fields in pure and applied mathematics. 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. EMS titles are distributed in the Americas by the American Mathematical Society.
