On overconvergent subsequencs of closed to rows classical Pade' approximants
Ralitza K. Kovacheva
Let be a power series with positive radius of convergence. In the present paper, we study the phenomenon of overconvergence of sequences of classical Pade' approximants pi{n,m_…
Zero Distribution of Hermite-Padé Polynomials and Convergence Properties of Hermite Approximants for Multivalued Analytic Functions
Nikolay R. Ikonomov, Ralitza K. Kovacheva, Sergey P. Suetin
In the paper, we propose two new conjectures about the convergence of Hermite Approximants of multivalued analytic functions of Laguerre class . The conjectures are b…
On the limit zero distribution of type I Hermite-Padé polynomials
Nikolay R. Ikonomov, Ralitza K. Kovacheva, Sergey P. Suetin
In this paper are discussed the results of new numerical experiments on zero distribution of type I Hermite-Padé polynomials of order for three different collections of thr…
Distribution of points of interpolation and of zeros of exact maximally convergent multipoint Padé approximants
R. K. Kovacheva
Given a regular compact set in the complex plane, a unit measure supported by a triangular point set $β:= \{\{β_{n,k}\}_{k=1}^n\}_{n=1}^{\infty},β\subset \par…
