Quantum (q, h)-Bézier surfaces based on bivariate (q, h)-blossoming

Demonstratio Mathematica, 2019
We introduce the (q, h)-blossom of bivariate polynomials, and we define the bivariate (q, h)-Bernstein polynomials and (q, h)-Bézier surfaces on rectangular domains using the tensor product.

Bell wavelets method to solve class of fractional differential equations arising in fluid mechanics

Partial Differential Equations in Applied Mathematics
This study introduces a new Bell wavelet matrix method to solve a class of fractional differential equations arising in fluid mechanics. The class under consideration comprises the fractional relaxation-oscillation equation (R-OE) as a special case.

Enhanced curve representations using piecewise non-linear binary subdivision scheme

Arab Journal of Basic and Applied Sciences
This study presents a piecewise non-linear binary subdivision scheme based on a four-point linear binary subdivision scheme. This scheme is first transformed into a piecewise linear subdivision scheme and then into a piecewise non-linear subdivision ...

Basc: Constrained Approximation by Semidefinite Programming

, 2016
This article details the theoretical grounds for a semidefinite-programming-based method that computes best approximants by splines under some general constraints and relative to several function norms, notably the max-norm.

ANALYSIS AND APPROXIMATION THEORY SEMINAR UNIVERSITY OF ALBERTA Construction of compactly supported biorthogonal wavelets in L 2 (IR s

, 2007
: This paper presents a general construction of compactly supported biorthogonal wavelets in L 2 (IR s ). In particular, a concrete method for the construction of bivariate compactly supported biorthogonal wavelets of increasing smoothness is provided.
