Asymptotic Properties of Discrete Minimal $s, l o g^{t}$ -Energy Constants and Configurations

Nichakan Loesatapornpipit, Nattapong Bosuwan

Combining the ideas of Riesz $s$ -energy and $lo g$ -energy, we introduce the so-called $s, lo g^{t}$ -energy. In this paper, we investigate the asymptotic behaviors for $N, t$ fixed and…

Direct and Inverse Results for Multipoint Hermite-Pade Approximants

N. Bosuwan, G. Lopez Lagomasino, Y. Zaldivar Gerpe

Given a system of functions f = (f1, . . . , fd) analytic on a neighborhood of some compact subset E of the complex plane, we give necessary and sufficient conditions for the conve…

Direct and inverse results on row sequences of simultaneous Padé-Faber approximants

N. Bosuwan, G. López Lagomasino

Given a vector function $F = (F_{1}, \dots, F_{d}),$ analytic on a neighborhood of some compact subset $E$ of the complex plane with simply connected complement, we define a sequenc…

Convergence of row sequences of simultaneous Padé-Faber approximants

Nattapong Bosuwan

We consider row sequences of vector valued Padé-Faber approximants (simultaneous Padé-Faber approximants) and prove a Montessus de Ballore type theorem.

Determining system poles using row sequences of orthogonal Hermite-Padé approximants

Nattapong Bosuwan, G. López Lagomasino

Given a system of functions $F = (F_{1}, \dots, F_{d}),$ analytic on a neighborhood of some compact subset $E$ of the complex plane with simply connected complement, we…
