Pointwise radial minimization: Hermite interpolation on arbitrary domains
In this paper we propose a new kind of Hermite interpolation on arbitrary domains, matching derivative data of arbitrary order on the boundary. The basic idea stems from an interpretation of mean value interpolation as the pointwise minimization of a radial energy function involving first derivatives of linear polynomials. We generalize this and minimize over derivatives of polynomials of arbit...
متن کاملFerreira : Interpolation in the Time and Frequency Domains 3
|In this paper we clarify the connections between two recently proposed and apparently unrelated approaches to band-limited interpolation, by showing that, in a certain sense made precise below, they are the dual of each other. The advantages of recognizing this duality are discussed.
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 کاملInterpolation Maps and Congruence Domains for Wavelet Sets
It is proven that if an interpolation map between two wavelet sets preserves the union of the sets, then the pair must be an interpolation pair. We also construct an example of a pair of wavelet sets for which the congruence domains of the associated interpolation map and its inverse are equal, and yet the pair is not an interpolation pair. The first result solves affirmatively a problem that t...
متن کاملPattern Mining in Sparse Temporal Domains, an Interpolation Approach
Weblog systems, mobile phone companies or GPS devices collect large amounts of personalized data including temporal, positional and textual information. Patterns extracted from such data can give insight in the behavior and mood of people. These patterns are often imprecise due to sparseness in the data. We propose an interpolation technique that augments local patterns with elements that seem ...
