The DeGruyter Studies in Mathematical Physics are devoted to the publication of monographs and
high-level texts in mathematical physics. They cover topics and methods in fields of current
interest with an emphasis on didactical presentation. The series will enable readers to
understand apply and develop further with sufficient rigor mathematical methods to given
problems in physics. For this reason works with a few authors are preferred over edited
volumes. The works in this series are aimed at advanced students and researchers in
mathematical and theoretical physics. They also can serve as secondary reading for lectures and
seminars at advanced levels.
