C^n中共轭全纯映射的映射

Maps conjugating holomorphic maps in C^n

Gregery T. Buzzard, Sergei Merenkov

摘要:

若f是从C^n到复流形M上的双射,且f使C^n中的每个全纯映射与M中的一个自同态共轭,则证明f必是双全纯或反双全纯的.这推广了A. Hinkkanen到更高的维度。作为推论,我们证明了:如果存在从C^n的全纯自同态半群到M的全纯自同态半群的满态映射,或对一个双传递的M存在一个相反方向的满态映射,则它是由某个双全纯或反双全纯映射共轭给出的.我们还证明了C^n中有两个无界域具有同构的自同态半群,但它们既不是双全纯等价的,也不是反双全纯等价的。

英文摘要:

If f is a bijection from C^n onto a complex manifold M, which conjugates every holomorphic map in C^n to an endomorphism in M, then we prove that f is necessarily biholomorphic or antibiholomorphic. This extends a result of A. Hinkkanen to higher dimensions. As a corollary, we prove that if there is an epimorphism from the semigroup of all holomorphic endomorphisms of C^n to the semigroup of holomorphic endomorphisms in M, or an epimorphism in the opposite direction for a doubly-transitive M, then it is given by conjugation by some biholomorphic or antibiholomorphic map. We show also that there are two unbounded domains in C^n with isomorphic endomorphism semigroups but which are neither biholomorphically nor antibiholomorphically equivalent.
