Web(11) Given a map ˚: X !X of a space X to itself, the mapping torus T ˚is the quotient of X [0;1] by the equivalence generated by (x;1) ˘(˚(x);0) for all x2X. Compute the homology groups H (T ˚) when (a) X= Sn and ˚has degree d, and (b) when X= Sn_Snand ˚interchanges the two spheres (so that ˚2 is the identity).
