Title: Symplectic embeddings of rational homology balls Abstract: We will begin with a description of the rational homology balls appearing in Fintushel and Stern's rational blow-down operation for smooth 4-manifolds, a generalization of the standard blow-down. We will then discuss various smooth and symplectic embedding results of these rational homology balls. Time permitting, we will also give some explicit constructions of such symplectic embeddings.
