Abstract:
Suppose that Pn are orthonormal polynomials on the closed interval [−1,1] which are constructed from a weight function satisfying the Szegö condition. In this paper, we obtain the first ellipse of meromorphy of the function F(z)=∑∞n=0FnPn(z), i.e., the maximal ellipse with foci at the points ±1 to which the function F can be extended as a meromorphic function having at most one pole.
