In this paper, we enumerate the equivalence classes of regular branched coverings of surfaces whose covering transformation groups are the direct sum of m copies of Z p , p prime.
Simple proofs of four theorems of \(\mathbf{K y}\) Fan on covering of simplexes by closed sets are presented. Open versions and reformulations of these theorems are also given. 1993 Academic Press, Inc.
## Abstract We consider closed bounded Choquet simplexes of tight measures on Hausdorff spaces. If the extreme boundary is closed, then each element is the barycenter of a uniquely determined tight probability measure on the extreme points. Consequently, on Hausdorff spaces tight exchangeable measu
## Abstract The empty set of course contains no computable point. On the other hand, surprising results due to ZaslavskiΔ, TseΔtin, Kreisel, and Lacombe have asserted the existence of nonβempty coβr. e. closed sets devoid of computable points: sets which are even βlargeβ in the sense of positive Le
