WebThe subsheaf F′ is obviously contained in the kernel of the natural map. If a section a∈ F(U) gives rise to the zero map in F(U)/F′(U) this implies that for some open cover of Uthe restrictions of ato the sets in this open cover are all in F′. This would imply that a∈ F′(U) because F′ is a sheaf. WebThe existence of universal unfoldings of certain germs of meromorphic connections is established. This is used to prove a general construction theorem for Frobenius manifolds. A particular case is Dubrovin’s theorem on semisimple Frobenius manifolds.
