On K-stability of Fano's last Fanos
Ivan Cheltsov, DongSeon Hwang, Alex Küronya +5
We study K-stability of smooth Fano threefolds of Picard rank and degree which can be obtained by blowing up a smooth complete intersection of two quadrics in $\mathbb{P}^…

Andrea Fanelli, Frédéric Mangolte
We study the connectedness of the real locus of smooth geometrically rational Fano threefolds and prove a sufficient criterion of -rationality.
