Abstract: We will see how holomorphic curves degenerate under a “multiple cut” of the symplectic manifold. In special cases, there is a correspondence between degenerated holomorphic curves and Mikhalkin’s tropical graphs, which are combinatorial objects lying in a plane. Consequently, the problem of counting holomorphic curves is reduced to the combinatorial problem of counting tropical graphs.
