W-algebras as conformal extensions of affine VOAs
Dražen AdamoviÄ, Tomoyuki Arakawa, Thomas Creutzig +4
The paper establishes criteria for when a homomorphism from an affine vertex algebra to another vertex superalgebra is conformal and surjective, and applies these criteria to W‑alg…
An abstract approach to algebras of braids and ties
Riccardo Fasano, Domenico Fiorenza, Paolo Papi
Generalizing work of Marin [12], we construct in a unified way all the "braids and ties'' algebras available in literature and new ones.
Spectral flow and application to unitarity of representations of minimal -algebras
Victor G. Kac, Pierluigi Möseneder Frajria, Paolo Papi
Using spectral flow, we provide a proof of [11, Theorem 9.17] on unitarity of Ramond twisted non-extremal representations of unitary minimal -algebras that does not rely on the…
Extremal unitary representations of big superconformal algebra
Victor G. Kac, Pierluigi Möseneder Frajria, Paolo Papi
In this paper we give a detailed proof of the classification of extremal (=massless) unitary highest weight representations in the Neveu Schwarz and Ramond sectors of the big …
