Abstract
In this paper, first we consider the existence and nonexistence of Einstein metrics on the topological 4-manifolds
3CP2 # k \bar{CP2}, the connected sum of CP2 with both choices of orientation,
by using the idea of Răsdeaconu-Şuvaina, 2009,
and the constructions in Park-Park-Shin, 2013.
Then, we study the existence or nonexistence of nonsingular solutions of the normalized Ricci flow on the exotic smooth structures of these topological manifolds by employing the obstruction developed in Ishida, 2008.
