Perverse Leray filtration and specialization with applications to the Hitchin morphism

MArk Andrea A de Cataldo

We initiate and develop a framework to handle the specialization morphism as a filtered morphism for the perverse, and for the perverse Leray filtration, on the cohomology with con…

On the P=W conjecture for

Mark Andrea A. de Cataldo, Davesh Maulik, Junliang Shen

Let be a prime number. We prove that the conjecture for is equivalent to the conjecture for . As a consequence, we verify the c…

Compactification of Dolbeault moduli spaces

Mark Andrea A. de Cataldo

We construct a relative compactification of Dolbeault moduli spaces of Higgs bundles for reductive algebraic groups on families of projective manifolds that is compatible with the…

The perverse filtration for the Hitchin fibration is locally constant

Mark Andrea A. de Cataldo, Davesh Maulik

We prove that the perverse Leray filtration for the Hitchin morphism is locally constant in families, thus providing some evidence towards the validity of the conjecture due…

Decomposition theorem for semi-simples

Mark Andrea de Cataldo

We use standard constructions in algebraic geometry and homological algebra to extend the decomposition and hard Lefschetz theorems of T. Mochizuki and C. Sabbah so that they remai…
