Effective homology and periods of complex projective hypersurfaces
Pierre Lairez, Eric Pichon-Pharabod, Pierre Vanhove
We introduce a new algorithm for computing the periods of a smooth complex projective hypersurface. The algorithm intertwine with a new method for computing an explicit basis of th…

Motivic geometry of two-loop Feynman integrals
Charles F. Doran, Andrew Harder, Eric Pichon-Pharabod +1
We study the geometry and Hodge theory of the cubic hypersurfaces attached to two-loop Feynman integrals for generic physical parameters. We show that the Hodge structure attached…
