Truncated factorized perverse sheaves on Sym(C)

Giovanna Carnovale, Francesco Esposito, Lleonard Rubio y Degrassi

Kapranov and Schechtman defined the category FP of factorized perverse sheaves on Sym(C) smooth along the stratification given by multiplicities and with values in a braided monoid…

Finite-dimensional pointed Hopf algebras over finite simple groups of Lie type VI. Suzuki and Ree groups

Giovanna Carnovale, Mauro Costantini

We analyse the rack structure of conjugacy classes in simple Suzuki and Ree groups and determine which classes are kthulhu. Combining this results with abelian rack techniques, we…

Hopf algebras over Chevalley groups

Nicolás Andruskiewitsch, Giovanna Carnovale

We show that every finite-dimensional pointed Hopf algebra over a finite simple Chevalley group, different from with q= 3 mod 4 (and from ), is…

Sheets, Jordan classes and induced orbits in the exotic and enhanced modules

Filippo Ambrosio, Giovanna Carnovale, Francesco Esposito +2

Kato developed an exotic Deligne-Langlands correspondence using a geometric model for the multiparameter affine Hecke algebra of type C, based on his exotic nilpotent cone. Achar-H…

Approximation of graded bialgebras

Giovanna Carnovale, Francesco Esposito, Lleonard Rubio y Degrassi

Motivated by an equivalence of categories established by Kapranov and Schechtman, we introduce, for each non-negative integer d, the category of connected bialgebras modulo d+1. We…

The versatility of the Drinfeld double of a finite group

Giovanna Carnovale, Nicola Ciccoli, Elena Collacciani

In this survey we review different instances in which the Drinfeld double of a finite group and its representations play a role, touching upon some of Tom Koornwinder's research in…
