On Quasi-Interpolation with Non-uniformly Distributed Centers on Domains and Manifolds
The paper studies quasi interpolation by scaled shifts of a smooth and rapidly decaying function. The centers are images of a smooth mapping of the hZn lattice in Rs, s n, and the scaling parameters are proportional to h. We show that for a large class of generating functions the quasi interpolants provide high order approximations up to some prescribed accuracy. Although the approximants do no...

15 صفحه اولSolving Interpolation Problems on Stiefel Manifolds Using Quasi-geodesics
The main objective of this paper is to propose a new method to generate smooth interpolating curves on Stiefel manifolds. This method is obtained from a modification of the geometric Casteljau algorithm on manifolds and is based on successive quasi-geodesic interpolation. The quasi-geodesics introduced here for Stiefel manifolds have constant speed, constant covariant acceleration and constant ...
متن کاملOn Analytic Interpolation Manifolds in Boundaries of Weakly Pseudoconvex Domains
Let Ω be a bounded, weakly pseudoconvex domain in Cn, n ≥ 2, with real-analytic boundary. A real-analytic submanifold M ⊂ ∂Ω is called an analytic interpolation manifold if every real-analytic function on M extends to a function belonging to O(Ω). We provide sufficient conditions for M to be an analytic interpolation manifold. We give examples showing that neither of these conditions can be rel...
متن کاملNetwork Location Problem with Stochastic and Uniformly Distributed Demands
This paper investigates the network location problem for single-server facilities that are subject to congestion. In each network edge, customers are uniformly distributed along the edge and their requests for service are assumed to be generated according to a Poisson process. A number of facilities are to be selected from a number of candidate sites and a single server is located at each facil...
