Posn(R) and Eisenstein Series
Lang S.
Posn(R)and Eisenstein Series provides an introduction, requiring minimal prerequisities, to the analysis on symmetric spaces of positive definite real matrices as well as quotients of this space by the unimodular group of integral matrices. The approach presented in very classical terms and includes material on speical functions, notably gamma and Bessel functions, and focuses on certain mathematical aspects of Eisenstein series.
