The enumeration of simultaneous higher-order contacts between plane curves
Using the Semple bundle construction, we derive an intersection-theoretic
formula for the number of simultaneous contacts of specified orders between
members of a generic family of degree plane curves and finitely many fixed
curves. The contacts counted by the formula occur at nonsingular points of both
the members of the family and the fixed curves.Comment: 32 pages, AmS-TeX v2.1 (Revised statement and proof of one lemma;

Cartan Prolongation of a Family of Curves Acquiring a Node
Using the monster/Semple tower construction, we study the structure of the
Cartan prolongation of the family of plane curves with nodal
central member
