A new family of isolated symplectic singularities with trivial local fundamental group
Gwyn Bellamy, Cédric Bonnafé, Baohua Fu +3
We construct a new infinite family of 4-dimensional isolated symplectic singularities with trivial local fundamental group, answering a question of Beauville raised in 2000. Three…
The localization spectral sequence in the motivic setting
Clément Dupont, Daniel Juteau
We construct and study a motivic lift of a spectral sequence associated to a stratified scheme, recently discovered by Petersen in the context of mixed Hodge theory and -adic…
Kumar's criterion modulo p
Daniel Juteau, Geordie Williamson
We prove that equivariant multiplicities may be used to determine whether attractive fixed points on T-varieties are p-smooth. This gives a combinatorial criterion for the determin…
Decomposition numbers for perverse sheaves
Daniel Juteau
The purpose of this article is to set foundations for decomposition numbers of perverse sheaves, to give some methods to calculate them in simple cases, and to compute them concret…
