Title
Enumerative geometry of curves in a moving family of surfaces.
Abstract: Enumerative geometry of curves in the complex projective plane is very classical. In this talk, we consider two generalisations of classical enumerative geometric problems of curves in the plane. We consider curves in that lie inside a in ; such curves are called planar curves. We discuss the enumeration of degree planar curves in having nodes and another singularity of codimension , and that intersect generic lines and pass through generic points in , where with . We also count the number of elliptic () curves of degree in a del Pezzo surface that pass through generic points of .
