Pentavalent arc-transitive Cayley graphs on Frobenius groups with soluble vertex stabilizer

open access: yesOpen Mathematics, 2019
A Cayley graph Γ is said to be arc-transitive if its full automorphism group AutΓ is transitive on the arc set of Γ. In this paper we give a characterization of pentavalent arc-transitive Cayley graphs on a class of Frobenius groups with soluble vertex ...

Changes to soil profile carbon and nutrient distribution following pasture renewal with full inversion tillage

open access: yesNew Zealand Journal of Agricultural Research, Volume 68, Issue 6, Page 1481-1501, December 2025.
ABSTRACT Full inversion tillage (FIT) at pasture renewal is a management option aiming to increase carbon stocks in long‐term pasture, to achieve carbon neutrality. This study investigated the effects of FIT on carbon and nutrient distribution in the soil profile (0–7.5, 7.5–15, 15–22.5 and 22.5–30 cm depths) as well as nutrient uptake, and subsequent ...

Neumaier Cayley graphs

open access: yes, 2023
A Neumaier graph is a non-complete edge-regular graph with the property that it has a regular clique. In this paper, we study Neumaier Cayley graphs. We give a necessary and sufficient condition under which a Neumaier Cayley graph is a strongly regular Neumaier Cayley graph. We also characterize Neumaier Cayley graphs with small valency at most $10$.

Boundary representations of locally compact hyperbolic groups

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 6, December 2025.
Abstract We develop the theory of Patterson–Sullivan measures for locally compact hyperbolic groups. This theory associates to certain left‐invariant metrics on the group measures on its boundary. Next, we establish irreducibility of the resulting (unitary) Koopman representations for second countable, nonelementary, unimodular locally compact ...

Cayley partitionable graphs

open access: yesElectronic Notes in Discrete Mathematics, 2000
Abstract In this paper we investigate the class of Cayley partitionable graphs. This investigation is motivated by the Strong Perfect Graph Conjecture. Cayley partitionable graphs are Cayley Graphs which are closely related to near-factorizations of finite groups. We prove some structural properties of near-factorizations and give examples of Cayley

ON (3,6) AND (4,6) - FULLERENE CAYLEY GRAPHS

open access: yesStudia Universitatis Babes-Bolyai Chemia, 2016
An (r, s)-fullerene graph is a planar 3-regular graph with only Cr and Cs faces, where Cn denotes a cycle of length n. In this paper, the (3,6)-fullerene Cayley graphs constructed from finite groups are classified.

Perfect state transfer in unitary Cayley graphs over local rings [PDF]

open access: yesTransactions on Combinatorics, 2014
In this work, using eigenvalues and eigenvectors of unitary Cayley graphs over finite local rings and elementary linear algebra, we characterize which local rings allowing PST occurring in its unitary Cayley graph.

Difference divisor graph of the finite group [PDF]

open access: yesInternational Journal of Research in Industrial Engineering, 2018
Let (Zn, +) be a finite group of integers modulo n and Dn a non-empty subset of Zn containing proper devisors of n. In this paper, we have introduced the difference divisor graph Diff (Zn, Dn) associated with Zn whose vertices coincide with Zn such that ...

Robust Bounds on the Eigenvalues of Linear Systems With Delays and Their Applications in Stability Analysis

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 35, Issue 16, Page 6636-6651, 10 November 2025.
ABSTRACT We review some known bounds on the eigenvalues of a matrix and use similar techniques to derive bounds for the class of nonlinear eigenproblems and, as a special case, the eigenvalues for LTI systems with delays. We present two classes of results.
