A second-order differential equation for the two-loop sunrise graph with arbitrary masses
Stefan Müller-Stach, Stefan Weinzierl, Raphael Zayadeh
We derive a second-order differential equation for the two-loop sunrise graph in two dimensions with arbitrary masses. The differential equation is obtained by viewing the Feynman…
Negative curves on algebraic surfaces
Th. Bauer, B. Harbourne, A. L. Knutsen +4
We study curves of negative self-intersection on algebraic surfaces. We obtain results for smooth complex projective surfaces X on the number of reduced, irreducible curves C of ne…
Abelian varieties and theta functions associated to compact Riemannian manifolds; constructions inspired by superstring theory
Stefan Müller-Stach, Chris Peters, Vasudevan Srinivas
We look into a construction of principal abelian varieties attached to certain spin manifolds, due to Witten and Moore-Witten around 2000 and try to place it in a broader framework…
On the relation between Nori Motives and Kontsevich Periods
Annette Huber, Stefan Müller-Stach
We show that the spectrum of Kontsevich's algebra of formal periods is a torsor under the motivic Galois group for mixed motives over the rational numbers. This assertion is stated…
