Nonuniform Coercions via Unification Hints [PDF]

Electronic Proceedings in Theoretical Computer Science, 2011
We introduce the notion of nonuniform coercion, which is the promotion of a value of one type to an enriched value of a different type via a nonuniform procedure.

On the Convexity Preservation of a Quasi C³ Nonlinear Interpolatory Reconstruction Operator on σ Quasi-Uniform Grids

Mathematics, 2021
This paper is devoted to introducing a nonlinear reconstruction operator, the piecewise polynomial harmonic (PPH), on nonuniform grids. We define this operator and we study its main properties, such as its reproduction of second-degree polynomials ...

Analysis of a New Nonlinear Interpolatory Subdivision Scheme on σ Quasi-Uniform Grids

Mathematics, 2021
In this paper, we introduce and analyze the behavior of a nonlinear subdivision operator called PPH, which comes from its associated PPH nonlinear reconstruction operator on nonuniform grids.

A Piecewise Polynomial Harmonic Nonlinear Interpolatory Reconstruction Operator on Non Uniform Grids—Adaptation around Jump Discontinuities and Elimination of Gibbs Phenomenon

Mathematics, 2021
In this paper, we analyze the behavior of a nonlinear reconstruction operator called PPH around discontinuities. The acronym PPH stands for Piecewise Polynomial Harmonic, since it uses piecewise polynomials defined by means of an adaption based on the ...

NONUNIFORM SUPER WAVELETS IN 𝐿^2(K)

Проблемы анализа, 2021
In this paper, we introduce the structure of nonuniform super wavelets over local fields. We shall also provide the characterization of nonuniform parseval frame, nonuniform semi-orthogonal pareseval multiwavelets, and nonuniform super wavelets over ...

Nonuniform Dichotomy with Growth Rates of Skew-Evolution Cocycles in Banach Spaces

Axioms, 2023
This paper presents integral charaterizations for nonuniform dichotomy with growth rates and their correspondents for the particular cases of nonuniform exponential dichotomy and nonuniform polynomial dichotomy of skew-evolution cocycles in Banach spaces.

Analysis of a nonuniform guiding structure by the adaptive finite-difference and singular value decomposition methods

ETRI Journal, 2023
This paper presents a flexible finite-difference technique for analyzing the nonuniform guiding structures. Because the voltage and current variations along the nonuniform structure differ for each segment, this work considers the adaptable ...
