Abstract

In this paper we describe the holomorphic automorphisms for two infinite series of Hermitian quadrics: quadrics of real co-dimension 2 in ℂⁿ⁺² and a special class of quadrics of co-dimension n in ℂ²ⁿ with large automorphism groups (Real Associative Quadrics).

We give explicit formulas of the automorphisms. They are rational maps of degree not exceeding the co-dimension.
