The torsion group
Webker are torsion groups because A is a torsion group. Hence the rst and third term of (2) are torsion. The result follows from the general result that if in an exact sequence 0 !G0!G !G00!0 the groups G0and G00are torsion, then so is G. 7.In the example of RP2 and the coe cient ring Z=2Z check the statement of the universal coe cient theorem in ...

Zachary DeStefano On the Torsion Subgroup of an Elliptic Curve WebThe torsion subgroup tD of any divisible group D is divisible, D=tD is a vector space over Qand D »= tD 'D=tD. Proof. Any x 2 tD is divisible by n > 0 in D. So there is a y 2 D s.t. ny = x. But then mny = mx = 0 for some m so y is torsion and lies in tD. Since tD is torsion it has a complement isomorphic to D=tD.
