拓扑学

　　亚尼齐编著的《拓扑学》内容介绍：This volume covers approximately the amount ofpoint-set topology that a student who does not intend to specializein the field should nevertheless know.This is not a whole lot, andin condensed form would occupy perhaps only a small booklet. Ouraim, however, was not economy of words, but a lively presentationof the ideas involved, an appeal to intuition in both the immediateand the higher meanings.
