In this paper the analytic continuation of the holomorphic discrete series is defined. The most elementary properties of these representations are developed. The study of when these representations ...

The series $\sum (m + nz)^{-s}, m, n$ ranging over all integers except both zero, for $s$ an integer greater than two is well known from the theory of elliptic ...

The quasiparticle concept is the foundation of our understanding of the dynamics of many-body quantum systems. It originated in metallic Fermi liquids with electron-like quasiparticles; but it is also ...
