Categorification of Lagrangian intersections on complex symplectic manifolds using perverse sheaves of vanishing cycles
Vittoria Bussi
We study intersections of complex Lagrangian in complex symplectic manifolds, proving two main results. First, we construct global canonical perverse sheaves on complex Lagrangian…
Generalized Donaldson-Thomas theory over fields K C
Vittoria Bussi
Generalized Donaldson-Thomas invariants defined by Joyce and Song arXiv:0810.5645 are rational numbers which `count' both -stable and -semistable coherent sheaves with Chern…
A 'Darboux Theorem' for shifted symplectic structures on derived Artin stacks, with applications
Oren Ben-Bassat, Christopher Brav, Vittoria Bussi +1
This is the fifth in a series arXiv:1304.4508, arXiv:1305,6302, arXiv:1211.3259, arXiv:1305.6428 on the '-shifted symplectic derived algebraic geometry' of Pantev, Toen, Vaquie…
Naive motivic Donaldson-Thomas type Hirzebruch classes and some problems
Vittoria Bussi, Shoji Yokura
Donaldson-Thomas invariant is expressed as the weighted Euler characteristic of the so-called Behrend (constructible) function. In \cite{Behrend} Behrend introduced a DT-type invar…
On motivic vanishing cycles of critical loci
Vittoria Bussi, Dominic Joyce, Sven Meinhardt
Let be a smooth scheme over an algebraically closed field of characteristic zero and a regular function, and write Crit, as a closed…
A 'Darboux theorem' for derived schemes with shifted symplectic structure
Christopher Brav, Vittoria Bussi, Dominic Joyce
We prove a 'Darboux theorem' for derived schemes with symplectic forms of degree , in the sense of Pantev, Toen, Vaquie and Vezzosi arXiv:1111.3209. More precisely, we show th…
