Optimum kernels

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2004
Kernel smoothers belong to the most popular nonparametric functional estimates. They provide a simple way of finding structure in data. Kernel smoothing can be very well applied on the regression model.

Fractional calculus and integral transforms of the product of a general class of polynomial and incomplete Fox–Wright functions

Advances in Difference Equations, 2020
Motivated by a recent study on certain families of the incomplete H-functions (Srivastava et al. in Russ. J. Math. Phys. 25(1):116–138, 2018), we aim to investigate and develop several interesting properties related to product of a more general ...

A Survey on Orthogonal Polynomials from a Monomiality Principle Point of View

Encyclopedia
This survey highlights the significant role of exponential operators and the monomiality principle in the theory of special polynomials. Using operational calculus formalism, we revisited classical and current results corresponding to a broad class of ...

Gegenbauer polynomials and the Fueter theorem [PDF]

Complex Variables and Elliptic Equations, 2013
The Fueter theorem states that regular (resp. monogenic) functions in quaternionic (resp. Clifford) analysis can be constructed from holomorphic functions in the complex plane, hereby using a combination of a formal substitution and the action of an appropriate power of the Laplace operator.

Polynomial cubic splines with tension properties [PDF]

, 2010
In this paper we present a new class of spline functions with tension properties. These splines are composed by polynomial cubic pieces and therefore are conformal to the standard, NURBS based CAD/CAM ...
