Abstract

It has been found experimentally by Brown and Schnetz that the number of points over Fp{\mathbb F}_p of a graph hypersurface is often related to the coefficients of a modular form. In this paper I prove this relation for one example of a modular form of weight 44 and two of weight 33, refine the statement and suggest a method of proving it for four more of weight 44, and use the one proved example to construct two new rigid Calabi-Yau threefolds that realize Hecke eigenforms of weight 44 (one provably and one conjecturally).
