Metric dimension and maximum eigenvalue multiplicity of graph Laplacians
Monther Rashed Alfuraidan, Suliman Khan, Lorenzo Sauras Altuzarra
We study equality between metric dimension and the maximum eigenvalue multiplicity of the Laplacian and signless Laplacian matrices. These quantities are not ordered in general. Us…
Multiplicity Bounds for Arbitrary Eigenvalues of Connected Signed Graphs
Monther R. Alfuraidan, Suliman Khan
The study of eigenvalue multiplicities plays a central role in the spectral theory of signed graphs, extending several classical results from the unsigned setting. While most exist…
Fixed point, Gregus-Ciric-contraction, monotone mappings, weighted graph
M. R. Alfuraidan, M. A. Khamsi
In this paper, we introduce the concept of monotone Gregus-Ćirić-contraction mappings in weighted digraphs. Then we establish a fixed point theorem for monotone Gregus-Ćirić-contra…
Coupled Fixed Points of monotone mappings in a metric space with a graph
M. R. Alfuraidan, M. A. Khamsi
In this work, we define the concept of mixed -monotone mappings defined on a metric space endowed with a graph. Then we obtain sufficient conditions for the existence of coupled…
Mann Iteration Process for Monotone Nonexpansive Mappings with a Graph
M. R. Alfuraidan
Let be a Banach space. Let be a nonempty, bounded, closed, and convex subset of and be a -monotone nonexpansive mapping. In this work, i…
On the non-existence of
Monther R. Alfuraidan, Ibrahim O. Sarumi, Sergey Shpectorov
We present a new non-existence proof for the strongly regular graph with parameters , using the unit vector representation of the graph.
A fixed point theorem for monotone asyptotic nonexpansive mappings
Monther Rashed Alfuraidan, Mohamed Amine Khamsi
Let C be a nonempty, bounded, closed, and convex subset of a Banach space X and be a monotone asymptotic nonexpansive mapping. In this paper, we investigate t…
