Generalized Hermite-Padé approximation for Nikishin systems of three functions
Nikishin systems of three functions are considered. For such systems, the rate of convergence of simultaneous interpolating rational approximations with partially prescribed poles is studied. The solution is described in terms of the solution of a vector equilibrium problem in the presence of a vector external field.

We improve the class of indices for which normality takes place in a Nikishin system and apply this in Hermite-Padé approximation of such systems of functions.
متن کاملRate of Convergence of Generalized Hermite-padé Approximants of Nikishin Systems
We study the rate of convergence of interpolating simultaneous rational approximations with partially prescribed poles to so called Nikishin systems of functions. To this end, a vector equilibrium problem in the presence of a vector external field is solved which is used to describe the asymptotic behavior of the corresponding second type functions which appear. 1. Generalized Hermite-Padé appr...
متن کاملThe Use of Generalized Gamma-Polynomial Approximation for Hazard Functions
We introduce a simple methodology, so-called generalized gamma-polynomial approximation, based on moment-matching technique to approximate survival and hazard functions in the context of parametric survival analysis. We use the generalized gamma-polynomial approximation to approximate the density and distribution functions of convolutions and finite mixtures of random variables, from which the ...
متن کاملRelative asymptotic of multiple orthogonal polynomials for Nikishin systems
We prove relative asymptotic for the ratio of two sequences of multiple orthogonal polynomials with respect to Nikishin system of measures. The first Nikishin system N (σ1, . . . , σm) is such that for each k, σk has constant sign on its compact support supp(σk) ⊂ R consisting of an interval e ∆k, on which |σ ′ k| > 0 almost everywhere, and a discrete set without accumulation points in R \ e ∆k...
