Abstract: Abstract Finding the number of maximal subgroups of infinite index of a finitely generated group is a natural problem that has been solved for several classes of “geometric” groups (linear groups, hyperbolic groups, mapping class… read more here.

Abstract: The subfactor theory provides a tool to analyze and construct extensions of Quantum Field Theories, once the latter are formulated as local nets of von Neumann algebras. We generalize some of the results of [62]… read more here.
