K. Saito and M. Saito prove that the universal unfolding of an isolated singularity
underlies a Frobenius manifold structure. Sabbah proves similar results
for universal unfoldings of nondegenerate convenient Laurent polynomials. We
study some ℓ-adic aspects of their works.
This is a work in progress.
