Maximizing Spectral Radii of Uniform Hypergraphs with Few Edges
Discussiones Mathematicae Graph Theory, 2016 In this paper we investigate the hypergraphs whose spectral radii attain the maximum among all uniform hypergraphs with given number of edges. In particular we characterize the hypergraph(s) with maximum spectral radius over all unicyclic hypergraphs ...

The girth alternative for mapping class groups [PDF]
arXiv, 2011 The girth of a finitely generated group G is the supremum of the girth of Cayley graphs for G over all finite generating sets. Let G be a finitely generated subgroup of the mapping class group Mod(S), where S is a compact orientable surface. Then, either G is virtually abelian or it has infinite girth; moreover, if we assume that G is not infinite ...

On the girth of infinite graphs
Discrete Mathematics, 1993 AbstractLet X be an infinite k-valent graph with polynomial growth of degree d, i.e. there is an integer d and a constant c such that fx(n)⩽cnd, where fx(n) denotes the growth function of X. We show that the girth of such a graph has an upper bound depending on c and d.

Some Metrical Properties of Lattice Graphs of Finite Groups
Mathematics, 2019 This paper is concerned with the combinatorial facts of the lattice graphs of Z p 1 × p 2 × ⋯ × p m , Z p 1 m 1 × p 2 m 2 , and Z p 1 m 1 × p 2 m 2 × p 3 1 .

Partition Parameters for Girth Maximum (m, r) BTUs [PDF]
arXiv, 2012 This paper describes the calculation of the optimal partition parameters such that the girth maximum (m, r) Balanced Tanner Unit lies in family of BTUs specified by them using a series of proved results and thus creates a framework for specifying a search problem for finding the girth maximum (m, r) BTU.
