Paths in quantum Cayley trees and L^2-cohomology

Roland Vergnioux

We study existence, uniqueness and triviality of path cocycles in the quantum Cayley graph of universal discrete quantum groups. In the orthogonal case we find that the unique path…

Invariants of the half-liberated orthogonal group

Teodor Banica, Roland Vergnioux

The half-liberated orthogonal group $O_{n}^{*}$ appears as intermediate quantum group between the orthogonal group $O_{n}$ , and its free version $O_{n}^{+}$ . We discuss here its basic algebr…
