Holomorphic versus algebraic equivalence for deformations of real-algebraic CR manifolds

Bernhard Lamel, Nordine Mir

Open full text 4 citations

Abstract

We consider (small) algebraic deformations of germs of real-algebraic CR submanifolds in complex space and study the biholomorphic equivalence problem for such deformations. We show that two algebraic deformations of minimal holomorphically nondegenerate real-algebraic CR submanifolds are holomorphically equivalent if and only if they are algebraically equivalent.
