## Non-generic tropical enumerative problems

##### Abstract:

Tropical geometry is useful not only in computing coarse (symplectically invariant) enumerative invariants (such as those coming from the Gromov-Witten theory), but also in more general enumerative problems, in particular, those involving special position of the constraints.\\ In the talk we'll look at those more general enumerative problems and show how they may be solved tropically.
