Birationally rigid complete intersections of quadrics and cubics

preprint2013arXivOpen access

Abstract

We prove birational superrigidity of generic Fano complete intersections VV of type 2k1⋅3k22^{k_1}\cdot 3^{k_2} in the projective space P2k1+3k2{\mathbb P}^{2k_1+3k_2}, under the condition that k2≥2k_2\geq 2 and k1+2k2=dimV≥12k_1+2k_2=\mathop{\rm dim} V\geq 12, and of a few families of Fano complete intersections of dimension 10 and 11. This is the third version: minor corrections were made, including a few typos.
