摘要

The rational homology balls B_n appeared in Fintushel and Stern's rational blow-down construction and were subsequently used in to construct exotic smooth manifolds with small Euler numbers. We show that a large class of smooth 4-manifolds have all the B_ns for odd n ≥ 3 embedded in them. In particular, we give explicit examples, using Kirby calculus, of several families of smooth embeddings of the rational homology balls B_n.
