Hodge theory and fluxes in weighted projective spaces: Galois action
Hugo Fortin, Daniel López Garcia
We extend the explicit study of -fluxes and general Hodge cycles from the ordinary Fermat sextic fourfold to tame Fermat-type hypersurfaces in weighted projective space. The m…

Hamiltonian actions on 0-shifted cosymplectic groupoids
Daniel López Garcia, Fabricio Valencia
We introduce the notion of 0-shifted cosymplectic structure on differentiable stacks and develop a corresponding moment map theory for Hamiltonian cosymplectic actions. We present…

On the monodromy action for
Daniel López Garcia, Fabricio Valencia
We solve the problem of determining under which conditions the monodromy of a vanishing cycle generates the whole homology of a regular fiber for a polynomial wh…
