The papers mainly on the Euclidean space collection series discussion on convergence of ∑AB in the Hausdorff distance. Our product of the two collections of definitions is different from general ways. And after the product collection is also maintaining the same dimensions. We also promote a space of dimension n-dimensional space. And found several sufficient conditions such as Dirichlet convergence, Holder’s generalization of the inequality and Mertens theorem. And we also used Li Junlin (2012) made by set some properties of the absolute convergence of series and the skills to finish or use some prayer of our papers.
