Let X → Y be a Galois covering of curves, where the genus of X is ≥ 2 and the genus of Y is ≤ 2. We prove that under certain hypotheses, X has an unramified cover that dominates a hyperelliptic curve; our results apply, for instance, to all tamely superelliptic curves. Combining this with a theorem of Bogomolov and Tschinkel shows that X has an unramified cover that dominates y = x − 1, if char...

in a study of 310 patients with suspected dermatophytic lesions, 110 cases of dermatophytosis, were diagnosed by direct smear in 10% koh and culture by two methods, skin stripping with use of adhesive tape and scrapping with scalpel blade conventional technique). out of 65 positive cultures, in 33 cases, growth was obtained by methods (scraping and stripping), 23 by the conventional technique a...

In this paper, some earlier results by Fleischner [H. Fleischner, Bipartizing matchings and Sabidussi’s compatibility conjecture, DiscreteMath. 244 (2002) 77–82] about edge-disjoint bipartizingmatchings of a cubic graphwith a dominating circuit are generalized for graphs without the assumption of the existence of a dominating circuit and 3-regularity. A pair of integer flows (D, f1) and (D, f2)...
