HOW TO CLASSIFY FANO VARIETIES? OLIVIER DEBARRE Abstract. We review some of the methods used in the classification of Fano varieties and the description of their birational geometry. Mori theory brought important simplif

ON PRIME FANO VARIETIES OF DEGREE 10 AND COINDEX 3 OLIVIER DEBARRE Abstract. According to Gushel and Mukai, most Fano varieties of degree 10, dimension n, and coindex 3 (index n−2) are obtained as linear sections of th

FANO VARIETIES AND EPW SEXTICS OLIVIER DEBARRE Abstract. We explore a connection between smooth projective varieties X of dimension n with an ample divisor H such that H n = 10 and KX = −(n − 2)H and a class of sexti

MODULI SPACES FOR CERTAIN FANO VARIETIES OLIVIER DEBARRE Abstract. It is yet unknown whether quasiprojective moduli spaces exist for all Fano varieties with finite automorphism groups. In this talk, we will describe a cl
