Let us consider a map from a $\Sigma_g \longrightarrow N$, where $N$ is a symplectic manifold.

Then we define the moduli space as

$M= \{ f | f \mbox{ is a pseudoholomorphic map } \Sigma_g \to N, f_* ([\Sigma]) = [A]\}$, where $A \in N$.

We assume the dimension of $N$ is $2n$.We We can cauculate the dimension of the moduli space $M$ is $n(2-2g)+c_1(A)$$n(2-2g)+2c_1(A)$

Questions: 1 Is the moduli space is non empty for any riemman surface and any N and any $[A] \in H_2(N)$ ?Questions:

2 Is there any simple way to dudge wether the moduli space is not empty? Or what about this problem when N is a four dimension manifold?

  1. Is the moduli space non-empty for any Riemman surface and any $N$ and any $[A] \in H_2(N)$ ?

  2. Is there any simple way to judge whether the moduli space is not empty? What about this problem when N is a four dimension manifold?

Sorry,there is my first time to use Tex andMost case I donn't konw howwant to addknow is N is a four-dimensional symplectic manifold with the back space. I beg your pardonfundamental group infinit.
