<p>The task is to express homology groups of SX through homology groups of X. (X is a simplicial complex)</p> <p>I don't really understand how to solve the problem.</p> <p>Every book, where i tried to read the explanation, operates with "reduced homology groups". And the solution is simple - <code>$H'_k(SX) = H'_{k-1}(X)$</code></p> <p>But i don't understand, how to move from reduced homology groups to ordinary homology groups.</p>
