Abstract: We describe the structure of totally disconnected minimal  bounded abelian groups by reducing the description to the case of those of them which are subgroups of powers of the adic integers . In this case the description is obtained by means of a functorial correspondence, based on Pontryagin duality, between topological and linearly topologized groups introduced by Tonolo. As an application we answer the question (posed in Pseudocompact and countably compact abelian groups: Cartesian products and minimality, Trans. Amer. Math. Soc. 335 (1993), 775790) when arbitrary powers of minimal bounded abelian groups are minimal. We prove that the positive answer to this question is equivalent to nonexistence of measurable cardinals.
