Monadic reconstruction of unitary Drinfeld centers and Factorization Homology

Lucas Hataishi

We prove that the unitary Drinfeld center of a unitary tensor category is equivalente to the category of unitary bimodules for the canonical W*-algebra object, generalizing Müger'…

Categorical dualtiy for Yetter-Drinfeld C*-algebras. Beyond the braided-commutative case

Lucas Hataishi, Makoto Yamashita

We develop a tensor categorical duality in the sprit of the Tannaka-Krein duality for the C*-algebras admitting the Yetter-Drinfeld module structure over a compact quantum group. U…

On the structure of DHR bimodules of abstract spin chains

Lucas Hataishi, David Jaklitsch, Corey Jones +1

Abstract spin chains axiomatize the structure of local observables on the 1D lattice which are invariant under a global symmetry, and arise at the physical boundary of 2+1D topolog…

Injectivity for algebras and categories with quantum symmetry

Lucas Hataishi, Makoto Yamashita

We establish the existence of injective envelopes for unital Yetter-Drinfeld C*-algebras, and a related class of bimodule categories over rigid C*-tensor categories. This implies m…

Inclusions of Operator Algebras from Tensor Categories: beyond irreducibility

Lucas Hataishi, Roberto Hernández Palomares

We derive faithful inclusions of C*-algebras from a coend-type construction in unitary tensor categories. This gives rise to different potential notions of discreteness for an incl…
