The purpose of the sequence is to give new and critical advancements in natural and utilized arithmetic. good tested locally over 20 years, it bargains a wide library of arithmetic together with numerous very important classics. The volumes offer thorough and distinctive expositions of the tools and concepts necessary to the subjects in query.

Spectral Problems in Geometry and Arithmetic: Nsf-Cbms Conference on Spectral Problems in Geometry and Arithmetic, August 18-22, 1997, University of Iowa

This paintings covers the court cases of the NSF-CBMS convention on 'Spectral difficulties in Geometry and mathematics' held on the college of Iowa. The vital speaker used to be Peter Sarnak, who has been a important contributor to advancements during this box. the quantity methods the subject from the geometric, actual, and quantity theoretic issues of view.

On the other hand by the similar argument to the proof of Theorem A we have the following. Proposition : qp,q(~) 15. E6/F4 symmetric R-spaces and U(n)/0(n). is rigid as a minimal isometric immersion. Finally we ask the following Problem. : For any other compact of exceptional type, is the first irreducible symmetric standard minimal space M immersion of M rigid ?
