On operator-valued measures
We consider positive operator-valued measures whose image is the bounded operators acting on an infinite-dimensional Hilbert space, and we relax, when possible, the usual assumption of positivity of the operator-valued measure seen in the quantum information theory literature. We consider integrals of quantum random variables, extending work done by Farenick--Plosker--Smith (2011) to the setting of infinite-dimensional Hilbert space, and develop positive operator-valued versions of a number of classical measure decomposition theorems. This is joint work with D. Mclaren and C. Ramsey. |

Isometries between substructures of operator algebras
In 1951, Kadison proved that every unital linear surjective isometry
between two unital C*-algebras is a Jordan *-isomorphism. In this talk,
I will survey some recent results on isometries between operator
algebras. We give the general form of surjective isometries between unit
spheres of two C*-algebras and between projection lattices of two von
Neumann algebras. This is partly a joint work with Narutaka Ozawa. |

Isometries between substructures of operator algebras II
I will explain further details about the talk one week before, in
particular on Tingley's problem for operator algebras. |

Generalized crossed products and discrete subfactors
We will describe a generalization of the crossed product construction for von Neumann algebras, where a group action on the algebra is replaced by a rigid C*-tensor category action on the algebra, together with a W*-algebra object internal to this category. Every spherical discrete extension of a II1 factor can be uniquely realized as such a crossed product. We will discuss some examples and applications. Based on joint work with David Penneys. |
