Group structure in finite coverings of compact solenoidal groups

Grigorian S.; Gumerov R.; Kazantsev A. (2000)

Let p : X → G be an n - fold covering of a compact solenoidal group G by a connected topological space X. We prove that there exists a group structure in X turning p into a homomorphism between compact abelian groups.
On a covering group theorem and its applications

Grigorian S.; Gumerov R. (2002)

Let p: X → G be an n-fold covering of a compact group G by a connected topological space X. Then there exists a group structure in X turning p into a homomorphism between compact groups. As an application, we describe all ...
On the structure of finite coverings of compact connected groups

Grigorian S.; Gumerov R. (2006)

Finite-sheeted covering mappings onto compact connected groups are studied. We show that for a covering mapping from a connected Hausdorff topological space onto a compact (in general, non-abelian) group there exists a ...
