In this question [1]: Induced map of homology groups of torus I couldn't understand the induced map on $H_1(X)$, $f_∗:H_1(X)→H_1(X)$ look like, how we define this map ?

    The same way you define induced maps on homology for any map of spaces? You can find the definition in any algebraic topology book. –  Jan 08 '16 at 15:37
  • @Mike this is general problem of me. I could not define the induce maps on homology. I read Hatcher Alg.Topology book but I haven't seen anything about it. – user365 Jan 08 '16 at 15:49
  • Have you tried the index at the back of the book? – Lee Mosher Jan 09 '16 at 03:17
  • @Lee soryy for delayed reply, I have looked but I didin't see anything about calculation about induced map. Do you think I overlook something? – user365 Jan 13 '16 at 11:06
  • Did you look up the word "induced" in the index? – Lee Mosher Jan 13 '16 at 14:39
