We will extend the Hasse-Weil zeta functions over finite fields F_q to plane curve singularities. There is a direct connection with the compactified Jacobians (from Fundamental Lemma), which will be explained. The functional equation holds for the corresponding L-functions (due to Galkin. 1976), but the Riemann hypothesis requires new approaches. The key is that the motivic superpolynomials (they will be defined) and L-functions depend on q polynomially, which is very different from the smooth case. They are conjectured to be topological invariants of the plane curve singularities. Presumably, the surface singularities related to Seifert 3-folds can result in q-deformations of the Riemann's zeta and the Dirichlet L-functions (if time permits).
