Invertible projective 2-representations from invertible 2d TQFTs with defects
Domenico Fiorenza, Chetan Vuppulury
We investigate invertible projective representations and their 2-categorical analogues using the language of TQFTs with defects. The main result is a freeness property for invertib…
Projective and anomalous representations of categories and their linearizations
Domenico Fiorenza, Chetan Vuppulury
We invesigate the relation between projective and anomalous representations of categories, and show how to any anomaly one can associate an…
A categorification of Kauffman states for planar graphs
Giovanni Cerulli Irelli, Domenico Fiorenza, Eugenio Landi +1
Given a decorated planar graph , where is a planar graph and with the directed medial graph of , we call some a…
-morphisms between twisted Courant -Lie algebras and untwisted Courant -Lie algebroids
Domenico Fiorenza, Antonio Michele Miti
In "Lie infinity algebras and higher analogues of Dirac structures and Courant algebroids" [arXiv:1003.1004], Marco Zambon constructs an -algebra associated with any high…
Computing the Khovanov homology of 2 strand braid links via generators and relations
Domenico Fiorenza, Omid Hurson
In "Homfly polynomial via an invariant of colored plane graphs", Murakami, Ohtsuki, and Yamada provide a state-sum description of the level Jones polynomial of an oriented link…
