Pointwise inner automorphisms of almost periodic factors
Cyril Houdayer, Yusuke Isono
We prove that a large class of nonamenable almost periodic type factors , including all McDuff factors that tensorially absorb and all free Araki-Woods…
Note on bi-exactness for creation operators on Fock spaces
Kei Hasegawa, Yusuke Isono, Tomohiro Kanda
In this note, we introduce and study a notion of bi-exactness for creation operators acting on full, symmetric and anti-symmetric Fock spaces. This is a generalization of our previ…
Boundary and rigidity of nonsingular Bernoulli actions
Kei Hasegawa, Yusuke Isono, Tomohiro Kanda
Let be a countable discrete group and consider a nonsingular Bernoulli shift action with two base points. When is exa…
Connes' bicentralizer problem for q-deformed Araki-Woods algebras
Cyril Houdayer, Yusuke Isono
Let be any strongly continuous orthogonal representation of on a real (separable) Hilbert space . For any , we den…
Ergodic theory of affine isometric actions on Hilbert spaces
Yuki Arano, Yusuke Isono, Amine Marrakchi
The classical Gaussian functor associates to every orthogonal representation of a locally compact group a probability measure preserving action of called a Gaussian action.…
Tensor product decompositions and rigidity of full factors
Yusuke Isono, Amine Marrakchi
We obtain several rigidity results regarding tensor product decompositions of factors. First, we show that any full factor with separable predual has at most countably many tensor…
