Rezumat

Let L be the class of locally compact abelian groups. For X 2 L; we denote by t(X) the torsion subgroup of X and by E(X) the ring of continuous endomorphisms of X; taken with the compact-open topology. If X is topologically torsion, then S(X) stands for the set of primes p such that the corresponding topological p-primary component of X is non-zero. Given a positive integer n; we set nX = fnx j x 2 Xg and X[n] = fx 2 X j nx = 0g:
