Hertling and Y. Manin. This new approach greatly simplifies the (classic) one used in the paper "Gauss-Manin systems, Brieskorn lattices and Frobenius structures (I)", written with C. Sabbah.26 pages, updated and extended version. Section 2 is slightly modified (we now consider more general deformations). Hertling and Manin's (GC) and (IC) conditions are detailed. The polynomial case is discussedAlgebraic Geometry32S40text
