Zeta function of projective hypersurfaces with ADE singularities

Algebraic Geometry 2022-01-05 v3 Number Theory

Abstract

Given a hypersurface, XX, prime pp, the zeta function is a generating function for the number of Fp\mathbb{F}_{p} rational points of XX. Until now, there is no algorithm for computing hypersurfaces with ADE singularities. Scott Stetson and Vladimir Baranovsky provided an algorithm with Mathematica for the ordinary double point case. In this paper, I go over a Sage algorithm for computing the zeta function of a hypersurface with ADE singularities over 3-dimensional projective space. To make the algorithm more efficient, I established an equivalence between a polynomial belonging to the Jacobian ideal with a polynomial satisfying a set of differential operators.
