Distinguished-root formulas for generalized Calabi-Yau hypersurfaces
Alan Adolphson, Steven Sperber
By a "generalized Calabi-Yau hypersurface" we mean a hypersurface in of degree dividing . The zeta function of a generic such hypersurface has a reciprocal…

A-hypergeometric series and the Hasse-Witt matrix of a hypersurface
Alan Adolphson, Steven Sperber
We give a short combinatorial proof of the generic invertibility of the Hasse-Witt matrix of a projective hypersurface. We also examine the relationship between the Hasse-Witt matr…
