现代几何学方法和应用 第3卷作者: B.A.DUBROVINA.T.FOMENKOS.P.NOVIKOV出版时间: 1999年版丛编项: Graduate Texts in Mathematics内容简介 In expositions of the elements of topology it is customary for homology to be given a fundamental role. Since Poincare, who laid the foundations of topology, homology theory has been regarded as the appropriate primary basis for an introduction to the methods of algebraic topology. From homotopy theory, on the other hand, only the fundamental group and covering-sp
