I want to know if there is a uniqueness (in any sense) theorem for the symplectic structure in a neighborhood of a symplectic surface in a four dimensional symplectic manifold. Or more generally for any configuartion of symplectic surfaces.

1$\begingroup$ Yes, of course. The neighborhood is determined by the type of the normal bundle. This follows from the DarbouxWeinstein Theorem. $\endgroup$– Robert BryantMay 16 '15 at 23:02

$\begingroup$ It seems to me DarbouxWeinstein is for a Lagrangian neighborhood, do you mean we can apply it to symplectic neighborhoods as well? $\endgroup$– nikitaMay 16 '15 at 23:40
Here is the version of the DarbouxWeinstein theorem that you want to use: Let $(M_1,\omega_1)$ and $(M_2,\omega_2)$ be symplectic manifolds of dimension $2n$ and let $\iota_i:P\to M_i$ be smooth embeddings with the property that there exists an isomorphism $\phi:\iota_1^*(TM_1)\to \iota_2^*(TM_2)$ of vector bundles such that $\phi^*(\omega_2) = \omega_1$ (i.e., $\phi$ is a symplectic isomorphism) and, moreover, $\phi(\iota_1'(v)) = \iota_2'(v)$ for all $v\in TP$. Then there exist open neighborhoods $U_i\subset M_i$ of $\iota_i(P)$ and a symplectomorphism $\Phi:(U_1,\omega_1)\to(U_2,\omega_2)$ such that $\Phi\circ\iota_1 = \iota_2$.
Thus, the symplectic structure near an embedded symplectic surface $P$ in a symplectic $4$manifold $(M,\omega)$ is determined by the isomorphism class of its (oriented) normal bundle (plus, of course, the symplectic area of $P$, i.e., the integral of $\omega$ over $P$).
