Abstract Given a function F holomorphic on a neighborhood of some compact subset of the complex plane, we prove that if the zeros of the denominators of generalized Padé approximants (orthogonal Padé approximants and Padé–Faber approximants) for

We investigated the energy of N points on an infinite compact metric space (A,d) of a diameter less than 1 that interact through the potential (1/ds)(log1/d)t, where s,t≥0 and d is the metric distance. With Elogts(A,N) denoting the minimal energy f

Hermite−Padé approximation has been a mainstay of approximation theory since the concept was introduced by Charles Hermite in his proof of the transcendence of e in 1873. This subject occupies a large place in the literature and it has application

Given a system of functions $${\mathbf {f}}=(f_1,\ldots ,f_d)$$ analytic on a neighborhood of some compact subset E of the complex plane with simply connected complement in the extended complex plane, we give necessary and sufficient conditions for t

Starting from the orthogonal and Faber polynomial expansions of a function F, we study the asymptotic behaviors of two generalized Pade approximations (orthogonal Pade approximation and Pade–Faber approximation). We obtain both direct and inverse r

Given a system of functions F = ( F 1 , … , F d ) , analytic on a neighborhood of some compact subset E of the complex plane with simply connected complement in the extended complex plane, we define a sequence of vector rational functions with comm

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

We consider row sequences of vector valued Padé-Faber approximants (simultaneous Padé-Faber approximants) and prove a Montessus de Ballore type theorem. Moreover, we provide a comparison between this new Montessus de Ballore type theorem and the Mo
