Spectral manipulation of the trigonometric Rosen-Morse potential through supersymmetry
David J. Fernández C., Rosa Reyes
The first and second-order supersymmetry transformations can be used to manipulate one or two energy levels of the initial spectrum when generating new exactly solvable Hamiltonian…

On the hyperbolicity constant of circular-arc graphs
R. Reyes, J. M. Rodriguez, J. M. Sigarreta +1
Gromov hyperbolicity is an interesting geometric property, and so it is natural to study it in the context of geometric graphs. It measures the tree-likeness of a graph from a metr…
