Popis: Inspired by a recent result of Levine-Lidman-Piccirillo, we construct infinitely many exotic smooth structures on some closed four-manifolds with definite intersection form and fundamental group isomorphic to $\Z /2\Z$. Similar constructions provide exotic smooth structures on further four-manifolds with fundamental group $Z/2\Z$, including examples with even $b_2^+$.
