Qudit stabilizers beyond the free case and the twisted Kitaev model
Ruslan Maksimau
We study the stabiliser formalism for qudits of arbitrary dimension . In the free case, we show that the basic theorem of the stabiliser formalism remains valid: if the stabilis…
Stratifying quiver Schur algebras via ersatz parity sheaves
Ruslan Maksimau, Alexandre Minets
We propose an extension of the theory of parity sheaves, which allows for non-locally constant sheaves along strata. Our definition is tailored for proving the existence of (proper…
Singularities in Calogero--Moser Varieties
Gwyn Bellamy, Ruslan Maksimau, Travis Schedler
In this article we describe completely the singularities appearing in Calogero--Moser varieties associated (at any parameter) to the wreath product symplectic reflection groups. We…
Flag versions of quiver Grassmannians for Dynkin quivers have no odd cohomology
Ruslan Maksimau
We prove the conjecture that flag versions of quiver Grassmannians (also known as Lusztig's fibers) for Dynkin quivers (types , , ) have no odd cohomology groups over an a…
