Some Properties of Hypergeometric Series Associated with Mirror Symmetry
Don Zagier, Aleksey Zinger
We show that certain hypergeometric series used to formulate mirror symmetry for Calabi-Yau hypersurfaces, in string theory and algebraic geometry, satisfy a number of interesting…

Period functions for Maass wave forms. I
J. Lewis, D. Zagier
Recall that a Maass wave form on the full modular group Gamma=PSL(2,Z) is a smooth gamma-invariant function u from the upper half-plane H = {x+iy | y>0} to C which is small as y \t…
