Higher-order asymptotics for the energy of greedy sequences on the unit circle
Abey López-García, Erwin Miña-Díaz
For the Riesz and logarithmic energies, we consider a greedy sequence of points on the unit circle constructed in such a way that for every integer $N\ge…
Relative asymptotics of multiple orthogonal polynomials for Nikishin systems of two measures
Abey López-García, Guillermo López Lagomasino
We study the relative asymptotics of two sequences of multiple orthogonal polynomials corresponding to two Nikishin systems of measures on the real line, the second one of which is…
Asymptotics of the optimal values of potentials generated by greedy energy sequences on the unit circle
Abey López-García, Erwin Miña-Díaz
For the Riesz and logarithmic potentials, we consider greedy energy sequences on the unit circle , constructed in such a way that for every , the…
Matrix continued fractions associated with lattice paths, resolvents of difference operators, and random polynomials
J. Kim, A. López-García, V. A. Prokhorov
We begin our analysis with the study of two collections of lattice paths in the plane, denoted and . These paths consist of sequences…
