Every connected sum of lens spaces is a real component of a uniruled algebraic variety  [ Toute somme connexe d'espaces lenticulaires est une composante réelle d'une variété algébrique uniréglée ]
Annales de l'Institut Fourier, Tome 55 (2005) no. 7, pp. 2475-2487.

Nous montrons qu'une somme connexe finie d'espaces lenticulaires est difféomorphe à une composante réelle d'une variété projective uniréglée et prouvons une conjecture de János Kollár.

We show that any finite connected sum of lens spaces is diffeomorphic to a real component of a uniruled projective variety, and prove a conjecture of János Kollár.
