Relations between some topological indices and the line graph
Walter Carballosa, Ana Granados, Domingo Pestana +2
The concepts of geometric-arithmetic and harmonic indices were introduced in the area of chemical graph theory recently. They have proven to correlate well with physical and chemic…
Geometric-Arithmetic index and line graph
Domingo Pestana, Jose María Sigarreta, Eva Tourís
The concept of geometric-arithmetic index was introduced in the chemical graph theory recently, but it has shown to be useful. The aim of this paper is to obtain new inequalities i…
Several extremal problems on graphs involving the circumference, girth, and hyperbolicity constant
Veronica Hernandez, Domingo Pestana, Jose M. Rodriguez
To compute the hyperbolicity constant is an almost intractable problem, thus it is natural to try to bound it in terms of some parameters of the graph. Let be…
Bounds on Gromov Hyperbolicity Constant
Veronica Hernandez, Domingo Pestana, Jose M. Rodriguez
If is a geodesic metric space and , a geodesic triangle is the union of the three geodesics , an…
Muckenhoupt inequality with three measures and applications to Sobolev orthogonal polynomials
E. Colorado, D. Pestana, J. M. Rodriguez +1
We generalize the classical Muckenhoupt inequality with two measures to three under appropriate conditions. As a consequence, we prove a simple characterization of the undedness of…
Computation of conformal representations of compact Riemann surfaces
Guillermo Lopez Lagomasino, Domingo Pestana, Jose M. Rodriguez +1
We find a system of two polynomial equations in two unknowns, whose solution allows to give an explicit expression of the conformal representation of a simply connected three sheet…
