Let F be an infinite division ring, V be a left F-vector space, \(r\ge 1\) be an integer. We study the structure of the representation of the linear group \(\mathrm {GL}_F(V)\) in the vector space of formal finite linear combinations of r-dimensional vector subspaces of V with coefficients in a field. This gives a series of natural examples of irreducible infinite-dimensional representations of projective groups. These representations are non-smooth if F is locally compact and non-discrete.



We are grateful to Leonid Rybnikov and Sasha Kazilo for bringing us together and providing an exceptional enviroment that made our work possible. The study has been funded within the framework of the HSE University Basic Research Program and the Russian Academic Excellence Project ‘5-100’. R.B. is partially supported by an NSF grant.
