Sharp Gromov Hyperbolicity Constants for Cartesian Products of Finitely Many Trees

Junior Michel, Anier Soria Lorente, Jean Marie-Vilaire

Let $X = T_{1} \times \dots \times T_{k}$ , $k \geq 2$ , be a Cartesian product of finite nontrivial trees with unit edges, and write $d_i=\diam T_i$, $S = \sum_{i} d_{i}$ and $M = max_{i} d_{i}$ . 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…

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…
