Approximation of Analytic Functions by Solutions of Cauchy-Euler Equation
Journal of Function Spaces, 2016 We investigate the approximation properties of a special class of twice continuously differentiable functions by solutions of the Cauchy-Euler equation.

Extension of Dasgupta’s Technique for Higher Degree Approximation
Universitas Scientiarum, 2021 In the present paper, rational wedge functions for degree two approximation have been computed over a pentagonal discretization of the domain, by using an analytic approach which is an extension of Dasgupta’s approach for linear approximation.

Polynomial Approximation of Functions Analytic in a Disk [PDF]
Proceedings of the American Mathematical Society, 1966 This result cannot be called completely unexpected, since there are earlier theorems in approximation theory which relate a bounded pth derivative of f to En(f) by a formula similar to (1) (compare Favard's theorem). We propose a new approach, based on Babenko's, yet simpler, and more general.

On Joint Approximation of Analytic Functions by Beurling Zeta-Functions
MathematicsFor j=1,…,r, let Pj be a system of generalized prime numbers, NPj the corresponding system of generalized integers, and ζPj(s), s=σ+it, the Beurling zeta-function. In the paper, we consider simultaneous approximation of a collection of analytic functions

Taylor’s series and approximation to analytic functions [PDF]
Bulletin of the American Mathematical Society, 1946 Taylor's series, as the simplest expansion in terms of rational functions of an arbitrary analytic function of a complex variable, has shown itself extremely useful as a guide to other such expansions. Taylor's series itself suggests other expansions and their properties, for instance series of polynomials defined by interpolation or best approximation,

Banach Spaces of Analytic Vector-valued Functions [PDF]
, 2007 The main theme of the thesis is the study of continuity and approximation problems, involving matrix-valued and vector-valued Hardy spaces on the unit disc ID and its boundary T in the complex plane.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Superoptimal Analytic Approximations of Matrix Functions
Journal of Functional Analysis, 1994 The paper deals with the problem of approximation of a bounded matrix function \(G\) on the unit circle by functions \(Q\) bounded and analytic in the unit disk. In the case of continuous \(G\) it is stated that there exists a unique \(Q\) such that \(G- Q\) minimizes the singular values. The structure of the error \(G-Q\) and smoothness properties of \

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.
