A. Vershik

The paper tells about the main features and events of the ergodic seminar organized and headed by V.~A.~Rokhlin at the Leningrad State University. The seminar was active in {\rm196…

Cohomology of Iwasawa subgroup of the group $U (p, p)$ in nonunitary representations

Anatoly Vershik, Mark Graev

We consider special nonuntary represenation of the Iwasawa subgrouh with a nontrivial cohomology. For $p > 2$ presunabley there are unitary representations with this property.

Cohomology in nonunitary representations of semisimple Lie groups (the group $U (2, 2)$ )

A. M. Vershik, M. I. Graev

We suggest a method of constructing special nonunitary representations of semisimple Lie groups using representations of Iwasawa subgroups. As a typical example, we study the group…
