Sharp Gromov Hyperbolicity Constants for Cartesian Products of Finitely Many Trees
Junior Michel, Anier Soria Lorente, Jean Marie-Vilaire
Let , , be a Cartesian product of finite nontrivial trees with unit edges, and write $d_i=\diam T_i$, and . We prove…
A reciprocal-Gamma Mehler--Heine limit for Krawtchouk--Sobolev type orthogonal polynomials with an exterior mass point
Anier Soria Lorente, Junior Michel
We study the monic polynomials $\Sob{n}$ orthogonal with respect to a Sobolev-type modification of the discrete Krawtchouk inner product in which a single point mass at an exterior…
Mehler--Heine asymptotics for finite differences of mass-modified Charlier and Meixner polynomials
Anier Soria-Lorente, Junior Michel
Point-mass perturbations and finite-difference operations alter the finite-degree structure of discrete orthogonal polynomials, but their combined effect at the Mehler--Heine scale…
ADPSO-ERLS: A Hybrid Discrete PSO with Enhanced Local Search for the Traveling Salesman Problem
Anier Soria-Lorente, Jean-Marie Vilaire, Junior Michel +1
The Traveling Salesman Problem is a canonical setting for studying how a population-based method should allocate a fixed search budget between exploration and progressively stronge…
On generating functions and Mehler--Heine formulas for discrete Charlier and Meixner Sobolev-type orthogonal polynomials
Anier Soria Lorente, Junior Michel
Generating functions are among the most important analytical tools in the theory of orthogonal polynomials, providing a unified framework for deriving structural identities, asympt…
