A Novel Algorithm for Nested Summation and Hypergeometric Expansions
Andrew J. McLeod, Henrik Munch, Georgios Papathanasiou +1
We consider a class of sums over products of Z-sums whose arguments differ by a symbolic integer. Such sums appear, for instance, in the expansion of Gauss hypergeometric functions…

A (Bounded) Bestiary of Feynman Integral Calabi-Yau Geometries
Jacob L. Bourjaily, Andrew J. McLeod, Matt von Hippel +1
We define the rigidity of a Feynman integral to be the smallest dimension over which it is non-polylogarithmic. We argue that massless Feynman integrals in four dimensions have a r…
