Finite-dimensional approximations for C*-algebras of product systems
Evgenios T. A. Kakariadis, Ioannis Apollon Paraskevas
We study C*-algebras generated by representations of product systems over unital subsemigroups of amenable discrete groups. In the first part, we show that exactness of the generat…
The reduced Hao-Ng isomorphism problem for product systems
Ioannis Apollon Paraskevas
We prove that the reduced Hao-Ng isomorphism problem has an affirmative answer for every generalised gauge action of a locally compact Hausdorff group on a product system over a un…
Morita equivalence for quantum graphs
Alexandros Chatzinikolaou, Gage Hoefer, Nikolaos Koutsonikos-Kouloumpis +1
We introduce an operator-algebraic framework for Morita equivalence of quantum graphs based on -equivalence of operator systems introduced by Eleftherakis, Kakariadis and Todoro…
On the embeddings of selfadjoint operator spaces
Alexandros Chatzinikolaou, Evgenios T. A. Kakariadis, Se-Jin Kim +1
We investigate when a map on a selfadjoint operator space is an embedding, i.e., when its unitisation in the sense of Werner is completely isometric. Combining with results of…
On hyperrigidity and non-degenerate C*-correspondences
Joseph A. Dessi, Evgenios T. A. Kakariadis, Ioannis Apollon Paraskevas
We revisit the results of Kim, and of Katsoulis and Ramsey concerning hyperrigidity for non-degenerate C*-correspondences. We show that the tensor algebra is hyperrigid, if and onl…
On Fock covariance for product systems and the reduced Hao-Ng isomorphism problem by discrete actions
Evgenios T. A. Kakariadis, Ioannis Apollon Paraskevas
We provide a characterisation of equivariant Fock covariant injective representations for product systems. We show that this characterisation coincides with Nica covariance for com…
Technical design of the phase I Mu3e experiment
K. Arndt, H. Augustin, P. Baesso +102
The Mu3e experiment aims to find or exclude the lepton flavour violating decay at branching fractions above . A first phase of the experiment using an…
