Perverse filtration on Hilbert schemes via upward flow

Filip Živanović

We explicitly compute the perverse Leray filtration on the top cohomology of the Hilbert scheme of points on , for any connected smooth projective curve . T…

Equivariant multiplicities and mirror symmetry for Hilbert schemes

Alexandre Minets, Filip Živanović

Following Hausel-Hitchin, we investigate core Lagrangians and upward flows in Hilbert schemes of points on elliptic surfaces. We compute the scheme-theoretic multiplicities of core…

Filtrations on quantum cohomology via Morse-Bott-Floer Spectral Sequences

Alexander F. Ritter, Filip Živanović

Using Morse-Bott-Floer spectral sequences, we describe a filtration by ideals on quantum cohomology for symplectic manifolds with a Hamiltonian -action that extends to a pseud…

Filtrations on quantum cohomology from the Floer theory of -actions

Alexander F. Ritter, Filip Živanović

We construct a filtration by ideals on quantum cohomology for symplectic manifolds with a Hamiltonian -action that extends to a pseudoholomorphic -action. These…

Floer-theoretic filtration on Painlevé Hitchin systems

Szilárd Szabó, Filip Živanović

We classify equivariant -actions on moduli spaces of Higgs bundles corresponding to the Painlevé equations. Using this, we compute the Floer-theoretic filtrations on…

Quantum cohomology and Floer invariants of semiprojective toric manifolds

Alexander F. Ritter, Filip Živanović

We use Floer theory to describe invariants of symplectic -manifolds admitting several commuting -actions. The -actions induce filtrations…
