Pancyclic Cayley Graphs [PDF]

open access: yes, 2012
2010 Mathematics Subject Classification: Primary 05C25. Secondary 20K01, 05C45.Let Cay(G;S) denote the Cayley graph on a finite group G with connection set S. We extend two results about the existence of cycles in Cay(G;S) from cyclic groups to arbitrary

Mobius Group Generated by Two Elements of Order 2, 4, and Reduced Quadratic Irrational Numbers

open access: yes, 2022
The construction of circuits for the evolution of orbits and reduced quadratic irrational numbers under the action of Mobius groups have many applications like in construction of substitution box (s-box), strong-substitution box (s.s-box), image ...

Two gluing methods for string C-group representations of the symmetric groups [PDF]

open access: yes
The study of string C-group representations of rank at least \(n/2\) for the symmetric group \(S_n\) has gained a lot of attention in the last fifteen years. In a recent paper, Cameron et al.

On finite presentability of direct products of semigroups

open access: yes, 2000
A finite semigroup S is said to preserve finite generation (resp., presentability) in direct products, provided that, for every infinite semigroup T, the direct product S x T is finitely generated (resp., finitely presented) if and only if T is finitely ...

Reconstructing Subsets of Reals [PDF]

open access: yes, 1999
We consider the problem of reconstructing a set of real numbers up to translation from the multiset of its subsets of fixed size, given up to translation.

Harmonic evolutions on graphs

open access: yes, 2008
We define the harmonic evolution of states of a graph by iterative application of the harmonic operator (Laplacian over Z2). This provides graphs with a new geometric context and leads to a new tool to analyze them.

A framework unifying some bijections for graphs and its connection to Lawrence polytopes [PDF]

open access: yes
Let \(G\) be a connected graph. The Jacobian group (also known as the Picard group or sandpile group) of \(G\) is a finite abelian group whose cardinality equals the number of spanning trees of \(G\).

A characterization of cayley graphs of Brandt semigroups

open access: yes, 2012
In this paper, first we characterize Cayley graphs of finite Brandt semigroups, and we give a criterion to check whether a finite digraph is a Cayley graph of a finite Brandt semigroup.
