DESCRIPTION:Tropical curves are piecewise linear analogues of
algebraic curves that share many of their properti
es. The tropical correspondence theorem of Mikhalk
in and Nishinou-Siebert states that rational plane
curves through general points can be counted trop
ically. Another natural enumerative problem is the
count (relative/log GW invariant) of plane curves
intersecting a fixed elliptic curve in exactly on
e (unspecified) point. In this talk I will explain
the tropical analogue of this counting problem.
