摘要

We study II1 factors M and N associated wit h good generalized Bernoulli actions of groups having an infinite almost normal Subgroup with the relative property (T). We prove the following rigidity result : every finite index M-N-bimodule (in particular. every isomorphism between All and N) is described by a commensurability of the groups involved Mid a commensurability of their actions. The fusion algebra of finite index M-M-bimodules is identified with an extended Hecke fusion algebra, providing the first explicit computations of the fusion algebra of a II1 factor We obtain in particular explicit examples of II1 factors with trivial fusion algebra, i.e. only having trivial finite index subfactors.
