Galois Groups of Symmetric Cubic Surfaces

Eric Pichon-Pharabod, Simon Telen

The Galois group of a family of cubic surfaces is the monodromy group of the 27 lines of its generic fibre. We describe a method to compute this group for linear systems of cubic s…

Periods of fibre products of elliptic surfaces and the Gamma conjecture

Eric Pichon-Pharabod

We provide an algorithm for computing a basis of homology of fibre products of elliptic surfaces over , along with the corresponding intersection product and period ma…

A semi-numerical algorithm for the homology lattice and periods of complex elliptic surfaces over the projective line

Eric Pichon-Pharabod

We provide an algorithm for computing an effective basis of homology of elliptic surfaces over the complex projective line on which integration of periods can be carried out. This…

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…
