AG : Cristian Vergu (Niels Bohr Institute) – 15h – Feynman integrals, their singularities and geometry
Exceptionnellement à 15h. Abstract: Feynman integrals, besides being useful in perturbative quantum field theories, are also a source of interesting transcendental functions such as multiple polylogarithms (or even more complicated and poorly understood classes of functions). Still, at present we
