关于几个加法定理的线性形式

On linear versions of some addition theorems

Shalom Eliahou, Cédric Lecouvey

摘要:

设K \subset L是域扩张。给定L的K-子空间A,B,研究了由积集AB = {ab| a \in A,b \in B}。我们得到了这个子空间的维数和dim B^n关于dim A,dim B和n的一些下界.这是通过建立线性版本的建设和结果,在加性数论主要是由于肯珀曼和奥尔森。

英文摘要:

Let K \subset L be a field extension. Given K-subspaces A,B of L, we study the subspace spanned by the product set AB = {ab | a \in A, b \in B}. We obtain some lower bounds on the dimension of this subspace and on dim B^n in terms of dim A, dim B and n. This is achieved by establishing linear versions of constructions and results in additive number theory mainly due to Kemperman and Olson.
