Graph Energy Maximisation for Integral Circulant Graphs of Order
Diego Roldan
The energy of a graph is the sum of the absolute values of its adjacency eigenvalues. For integral circulant graphs $\ICG(n,\mathcal{D})$ of order , where and are…

The Quantum Walk Characteristic Polynomial Distinguishes All Strongly Regular Graphs of Prime Orde
Diego Roldan
Let be a strongly regular graph of prime order with connection degree . We prove that the \emph{quantum walk characteristic polynomial} $χ_q(G,λ) \coloneqq \det(λ…

The Lorentz factor in a reverse coordinate system
Diego Roldan, Rodrigo Sempertegui, Francisco Roldan
In the present study, we have derived the Lorentz factor using a coordinate system with antiparallel X-axes. Using a thought experiment, common in relativistic literature, we have…
