After the seminal works by T. J. Stieltjes and E. Heine in the last third of the 19th century about the electrostatic interpretation of zeros of classical families of orthogonal polynomials (Jacobi, Laguerre, Hermite), as well as on the now called Heine-Stieltjes polynomials, a number of extensions of this elegant approach have been considered. In this talk we give an electrostatic model for the so-called multiple orthogonal polynomials (also known Hermite-Padé polynomials). We particularly focus on the well known Angelesco and Nikishin settings.
This is a joint work with A. Martínez Finkelshtein (Baylor Univ., TX, USA, and Almería Univ., Spain) and J. Sánchez Lara (Granada Univ., Spain).
