Coherent sheaves on surfaces, COHAs and deformed $W_{1 + \infty}$ -algebras

Anton Mellit, Alexandre Minets, Olivier Schiffmann +1

We compute the cohomological Hall algebra of zero-dimensional sheaves on an arbitrary smooth quasi-projective surface $S$ with pure cohomology, deriving an explicit presentation by…

$P = W$ via $H_{2}$

Tamas Hausel, Anton Mellit, Alexandre Minets +1

Let $H_{2}$ be the Lie algebra of polynomial Hamiltonian vector fields on the symplectic plane. Let $X$ be the moduli space of stable Higgs bundles of fixed relatively prim…
