Enumerating branched coverings over surfaces with boundaries
The number of nonisomorphic n-fold branched coverings over a given surface with a boundary is determined by the number of nonisomorphic n-fold graph coverings over a suitable bouquet of circles. A similar enumeration can be done for regular branched coverings. Some explicit formulae for enumerations are also obtained. © 2003 Elsevier Ltd. All rights reserved. MSC 2000: 05C10; 05C30; 57M12
متن کاملEnumerating branched orientable surface coverings over a non-orientable surface
The isomorphism classes of several types of graph coverings of a graph have been enumerated by many authors [M. Hofmeister, Graph covering projections arising from finite vector space over finite fields, Discrete Math. 143 (1995) 87–97; S. Hong, J.H. Kwak, J. Lee, Regular graph coverings whose covering transformation groups have the isomorphism extention property, Discrete Math. 148 (1996) 85–1...
متن کاملEnumerating simplicial decompositions of surfaces with boundaries
It is well-known that the triangulations of the disc with n + 2 vertices on its boundary are counted by the nth Catalan number C(n) = 1 n+1 ` 2n
متن کاملEnumeration of the Branched Zp-Coverings of Closed Surfaces
A continuous function p : S̃ → S between two surfaces S̃ and S is called a branched covering if there exists a finite set B in S such that the restriction of p to S̃ − p−1(B), p | S̃−p−1(B) : S̃− p −1(B)→ S− B, is a covering projection in the usual sense. The smallest set B of S which has this property is called the branch set. A branched covering p : S̃ → S is regular if there exists a (finite) grou...
متن کاملRepresenting Dehn Twists with Branched Coverings
We show that any homologically non-trivial Dehn twist of a compact surface F with boundary is the lifting of a half-twist in the braid group Bn, with respect to a suitable branched covering p : F → B. In particular, we allow the surface to have disconnected boundary. As a consequence, any allowable Lefschetz fibration on B is a branched covering of B × B.
