Genus Spectra for Split Metacyclic Groups
An integer n ! 2 is said to be a genus of a finite group G if there is a compact Riemann surface of genus n on which G acts as a group of automorphisms. In this paper, formulae are given for the minimum genus, minimum stable genus and the gap sequence, i.e., the (finite) set of non-genera, for a split metacyclic group of order pq, where p and q are primes. This information completely determines...
متن کاملThe non-orientable genus of some metacyclic groups
In the case of a 2-cell embedding (i.e., in the case where every region of the embedding is homeomorphic to a disk), the'inequality can easily be derived from the Euler Formula, v e + f = 2 2"fwhere e is the number of edges and f is the number of 2-cells of the embedding): the Handshaking Lemma asserts 2e = dv, and applying the Handshaking Lemma to the dual graph yields 2e >. gf; incorporating ...
متن کاملCharacter Tables of Metacyclic Groups
We show that two metacyclic groups of the following types are isomorphic if they have the same character tables: (i) split metacyclic groups, (ii) the metacyclic p-groups and (iii) the metacyclic {p, q}-groups, where p, q are odd primes. 2010 Mathematics Subject Classification.

متن کاملFibonacci lengths for certain metacyclic groups
For a finitely generated group G = 〈A〉 where A = {a1, a2, . . . , an} the sequence xi = ai+1, 0 ≤ i ≤ n − 1, xi+n = ∏n j=1 xi+j−1, i ≥ 0, is called the Fibonacci orbit of G with respect to the generating set A, denoted FA(G). If FA(G) is periodic we call the length of the period of the sequence the Fibonacci length of G with respect to A, written LENA(G). In this paper we examine the Fibonacci ...
متن کاملQUASI-PERMUTATION REPRESENTATIONS OF METACYCLIC 2-GROUPS
By a quasi-permutation matrix we mean a square matrix over the complex field C with non-negative integral trace. Thus, every permutation matrix over C is a quasipermutation matrix. For a given finite group G, let p(G) denote the minimal degree of a faithful permutation representation of G (or of a faithful representation of G by permutation matrices), let q(G) denote the minimal degree of a fa...
