We also analyze the relation between deformations of Frobenius modules and certain maximally degenerate variations of Hodge structures. Finally, under a certain generation hypothesis, we show how to construct a Frobenius manifold starting from a deformation of a Frobenius module.Typos correctedAlgebraic Geometry14D07 (Primary) 14J32, 32G20, 32S35 (Secondary)text
