Best Approximation Results for Fuzzy-Number-Valued Continuous Functions

Axioms, 2023
In this paper, we study the best approximation of a fixed fuzzy-number-valued continuous function to a subset of fuzzy-number-valued continuous functions.

Canonical Sets of Best L1-Approximation

Journal of Function Spaces and Applications, 2012
In mathematics, the term approximation usually means either interpolation on a point set or approximation with respect to a given distance. There is a concept, which joins the two approaches together, and this is the concept of characterization of the ...

Best Simultaneous Approximation in Orlicz Spaces

International Journal of Mathematics and Mathematical Sciences, 2007
Let X be a Banach space and let LΦ(I,X) denote the space of Orlicz X-valued integrable functions on the unit interval I equipped with the Luxemburg norm. In this paper, we present a distance formula dist(f1,f2,LΦ(I,G))Φ, where G is a closed subspace of X,

BEST APPROXIMATION AND BEST SIMULTANEOUS APPROXIMATION IN ULTRAMETRIC SPACES

Demonstratio Mathematica, 1996
A metric space \(X\) is ultrametric if the metric \(d\) satisfies the strong triangle inequality \(d(x,y)\leq\max\{d(x,z),d(z,y)\}\) for every \(x,y,z\in X\). The author considers various best approximation problems in an ultrametric setting and their relationship with the proximinal property.

Best approximation in Chebyshev subspaces of L(l_{1}^{n},l_{1}^{n}) [PDF]

Opuscula Mathematica, 2009
Chebyshev subspaces of \(\mathcal{L}(l_1^n,l_1^n)\) are studied. A construction of a \(k\)-dimensional Chebyshev (not interpolating) subspace is given.

Best approximation in b-modular spaces

مجلة بغداد للعلوم
In this paper, some basic notions and facts in the b-modular space similar to those in the modular spaces as a type of generalization are given.  For example, concepts of convergence, best approximate, uniformly convexity etc.

A topological approach to Best Approximation Theory

Applied General Topology, 2004
The main goal of this paper is to put some light in several arguments that have been used through the time in many contexts of Best Approximation Theory to produce proximinality results. In all these works, the main idea was to prove that the sets we are

Association Between Dinutuximab Beta Exposure and Post‐End‐of‐Treatment Survival in Neuroblastoma: A Weighted Patient‐Level Analysis of Three Clinical Studies

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives The association between exposure to dinutuximab beta (DB) and event‐free survival (EFS) or overall survival (OS) of neuroblastoma patients was assessed using data collected during three clinical trials (five cohorts). Methods A systematic review (March 2026) was conducted to identify relevant studies (prospective; registered DB ...

Measurable Residual Disease Monitoring During Treatment for Pediatric Acute Myeloid Leukemia in First Relapse

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survival after relapse in pediatric acute myeloid leukemia (AML) remains poor, highlighting the critical importance of identifying prognostic factors to guide optimal relapse management. Methods We investigated the prognostic impact of multiparameter flow cytometry (MFC) measurable residual disease (MRD) in 188 patients with first ...

A RESULT ON BEST APPROXIMATION

Tamkang Journal of Mathematics, 1998
Using a common fixed point theorem for noncommuting mappings of Pant [4], we improve and extend a result of Sahab, Khan and Sessa [5] on best approximation.
