Approximation of Functions in Besov Space

Radial Variation of Functions in Besov Spaces

Abstract This paper considers the radial variation function F (r, t) of an analytic function f(z) on the disc D. We examine F (r, t) when f belongs to a Besov space Apq and look for ways in which F imitates the behaviour of f . Regarded as a function of position (r, t) in D, we show that F obeys a certain integral growth condition which is the real variable analogue of that satisfied by f . We ...

Space Efficient Approximation of Piecewise Linear Functions

In this work, we compute upper bounds of piecewise linear functions which is a special case of piecewise linear approximation. There are several application areas like pattern recognition or cartography. The goal is to reduce the number of sampling points while still preserving the characteristics of given data. The problem of approximating a given piecewise linear function with n sampling poin...

APPROXIMATION OF 3D-PARAMETRIC FUNCTIONS BY BICUBIC B-SPLINE FUNCTIONS

In this paper we propose a method to approximate a parametric 3 D-function by bicubic B-spline functions

a contrastive study of rhetorical functions of citation in iranian and international elt scopus journals

writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
