WebFor the wedge sum, we have H~ n(S 1 _S1 _S2) = H~ n(S 1) H~ n(S 1) H~ n(S 2) and by noting that H n(Sk) = Z for n= kand n= 0 and zero otherwise, we obtain the same homology groups. For the second part, the universal covering space R2 of the torus S1 S1 is contractible, so H 0(R2) = Z while all others are zero.Thus, we only need one n6= 0 such … WebFor the wedge sum, we have H~ n(S 1 _S1 _S2) = H~ n(S 1) H~ n(S 1) H~ n(S 2) and by noting that H n(Sk) = Z for n= kand n= 0 and zero otherwise, we obtain the same …
