Algebraic realization of noncommutative near-group fusion categories

نویسندگان

چکیده

Noncommutative near-group fusion categories were completely classified in the previous work of first named author by using an operator algebraic method (and hence under assumption unitarity), and they shown to be group theoretical though corresponding pointed not identified. In this note we give a purely construction noncommutative starting from categorically Morita equivalent them.

Near-group fusion categories and their doubles

A near-group fusion category is a fusion category C where all but 1 simple objects are invertible. Examples of these include the Tambara-Yamagami categories and the even sectors of the D (1) 5 and E6 subfactors, though there are infinitely many others. We classify the near-group fusion categories, and compute their doubles and the modular data relevant to conformal field theory. Among other thi...

Braided Near-group Categories

A near-group category is an additively semisimple category with a product such that all but one of the simple objects is invertible. We classify braided structures on near-group categories, and give explicit numerical formulas for their associativity and commutativity morphisms. 1. Results We consider near-group categories; that is, semisimple monoidal categories, whose set of simples consists ...

Algebraic Realization of Manifolds with Group Actions

Let G be a compact Lie group and M a closed smooth G manifold. With some restrictions on G or on the isotropy groups of the action we show that M is algebraically realized, i. e., there exists a non-singular real algebraic G variety which is equivariantly diffeomorphic to M .

Algebraic Group Actions on Noncommutative Spectra

Let G be an affine algebraic group and let R be an associative algebra with a rational action of G by algebra automorphisms. We study the induced G-action on the set Spec R of all prime ideals of R, viewed as a topological space with the Jacobson-Zariski topology, and on the subspace Rat R ⊆ Spec R consisting of all rational ideals of R. Here, a prime ideal P of R is said to be rational if the ...

Algebraic Realization for Cyclic Group Actions

Suppose G is a finite cyclic group and M a closed smooth G–manifold. In this paper we will show that there is a nonsingular real algebraic G–variety X which is equivariantly diffeomorphic to M and all G–vector bundles over X are strongly algebraic.
