I will first recall the definition of an invariant that assigns to any compact subset $K$ of a closed symplectic manifold $M$ a module $SH_M(K)$ over the Novikov ring. I will go over the case of $M=S^2$ to illustrate various points about the invariant. Finally I will state the Mayer-Vietoris property and explain under what conditions it holds.
