Abstract

In this paper, we establish general stratawise higher jet evaluation transversality of JJ-holomorphic curves for a generic choice of almost complex structures JJ tame to a given symplectic manifold (M,ω)(M,\omega). Using this transversality result, we prove that there exists a subset \CJωram\CJω\CJ_\omega^{ram} \subset \CJ_\omega of second category such that for every J\CJωramJ \in \CJ_\omega^{ram}, the dimension of the moduli space of (somewhere injective) JJ-holomorphic curves with a given ramification profile goes down by 2n2n or 2(n1)2(n-1) depending on whether the ramification degree goes up by one or a new ramification point is created. We also derive that for each J\CJωramJ \in \CJ_\omega^{ram} there are only a finite number of ramification profiles of JJ-holomorphic curves in a given homology class βH2(M;Z)\beta \in H_2(M;\Z) and provide an explicit upper bound on the number of ramification profiles in terms of c1(β)c_1(\beta) and the genus gg of the domain surface.
