Query: Counting curves on surfaces: a guide to new techniques and results   This is a survey describing recents developments in enumerative geometry of
curves on projective varieties. Various methods to arrive at results such as
Kontsevich's formula for plane rational curves, or Caporaso-Harris's formula
for plane curves of any genus, are illustrated on concrete examples It will
appear on the Proceedings of the European Congress of Mathematics, Budapest
1996.
