Decomposability of quotients by complex conjugation for rational and Enriques surfaces

Abstract

The quotients $Y=X/conj$ by the complex conjugation $conjX\to X$ for complex rational and Enriques surfaces $X$ defined over $\mathbb{R}$ are shown to be diffeomorphic to connected sums of $\barCP2$, whenever $Y$ are simply connected.
