Popis: | A classical example of Mumford gives a generically non-reduced component of the Hilbert scheme of smooth curves in P3 such that a general element of the component is contained in a smooth cubic surface in P3. In this article we use techniques from Hodge theory to give further examples of such (generically non-reduced) components of Hilbert schemes of smooth curves without any restriction on the degree of the surface containing it. As a byproduct we also obtain generically non-reduced components of certain Hodge loci. |
