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…

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…
