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 $\ell$-adic aspects of their works. This is a work in progress.
