《代数拓扑讲义(英文版)》讲述了：This is essentially a book on singular homology and cohomology withspecial emphasis on products and manifolds. It does not treat homotopytheory except for some basic notions, some examples, and some applica-tions of homology to homotopy. Nor does it deal with general（ised）homology, but many formulations and arguments on singular homologyare so chosen that they also apply to general homology. Because of theseabsences I have also omitted spectral sequences, their main applicationsin topology being to homotopy and general homology theory. ech-cohomology is treated in a simple ad hoc fashion for locally compactsubsets of manifolds; a short systematic treatment for arbitrary spaces,emphasizing the universal property of the （ech-procedure, is containedin an appendix.The book grew out of a one-year's course on algebraic topology, and itcan serve as a text for such a course. For a shorter basic course, say ofhalf a year, one might use chapters Ⅱ Ⅲ Ⅳ（§1-4）, Ⅴ（§I-5, 7, 8）,Ⅵ（§ 3, 7, 9, 11, 12）. As prerequisites the student should know theelementary parts of general topology, abelian group theory, and thelanguage of categories-although our chapter Ⅰprovides a little helpwith the latter two. For pedagogical reasons, I have treated integralhomology only up to chapter Ⅵ if a reader or teacher prefers tohave general coefficients from the beginning he needs to make only minoradaptions.As to the outlay of the book, there are eight chapters, Ⅰ-Ⅷand nappendix, A; each of these is subdivided into several
