Some notes on trigonometric approximation of alpha psi differentiable functions in weighted variable exponenet Lebesgue spaces
(A. Razmadze Mathematical Institute, 2013)Improved Bernstein type inequality obtained and some inequalities of simultaneous approximation by trigonometric polynomials are proved. Also we proved an inverse theorem for functions having (α, ψ) derivatives in weighted ... -
Sharp Jackson and converse theorems of trigonometric approximation in weighted Lebesgue spaces
(2010)In the present work we prove that improved Jackson type direct theorem of trigonometric polynomial approximation in Lebesgue spaces with Muckenhoupt weights with respect to fractional order moduli of smoothness holds. ... -
Characterization of mixed modulus of smoothness in weighted Lp spaces
(Publishing House of the Romanian Academy, 2016)The paper is concerned with estimates for the mixed modulus of smoothness in Lebesgue spaces with Muckenhoupt weights, Steklov type averages. -
Approximation in smirnov-orlicz classes
(Drazen Adamoviç Üniversitesi, 2005)We use the approximation properties of the Faber polynomials to obtain some direct theorems of the polynomial approximation in Smirnov-Orlicz classes. -

Approximation by trigonometric polynomials in weighted morrey spaces
(Independent University of Moscow, 2024)In this work, some direct and inverse theorems of approximation theory in the weighted Morrey space are proved. The Lipschitz classes of functions in term of fractional modulus of smoothness are defined and their constructive ... -
Near best approximation property of interpolation and Poisson polynomials in weighted variable exponent Smirnov classes
(Hacettepe University, 2024)Let G be a bounded Jordan domain in the complex plane C. In this work under some restrictions of G the near best approximation property of complex interpolation and Poisson polynomials based on the Faber polynomials of G ... -
Ultra filters and quasi-subalgebras of Sheffer stroke BL-algebras based on the bipolar-valued fuzzy environment
(University of Nis, 2024)The notion of bipolar-valued filters and quasi-subalgebras of Sheffer stroke BL-algebras are introduced, and several properties are investigated. The relations among between a bipolar-valued fuzzy set, a bipolar-valued ... -
Enhancing maize foliar disease management through fractional optimal control strategies
(Amer Inst Mathematical Sciences-Aims, 2024)ct. Major yield losses in maize fields are being caused by a variety of foliar diseases. Early detection of these diseases can lower the possibility of extensive crop damage and assist farmers with setting up the ideal ... -
A new encoding/decoding algorithm via Fibonacci-Lucas tree diagrams
(World Scientific, 2024)In this paper, we present a new encoding and decoding method based on the recently introduced Minesweeper Model. Here, the main idea is to use Fibonacci-Lucas tree diagrams, and this proposed method uses a public key and ... -
Optimal control of microcephaly under vertical transmission of Zika
(MDPI, 2024)The Zika virus, known for its potential to induce neurological conditions such as microcephaly when transmitted vertically from infected mothers to infants, has sparked widespread concerns globally. Motivated by this, we ... -
Analysis of novel fractional order plastic waste model and its effects on air pollution with treatment mechanism
(Journal of Applied Analysis and Computation, 2024)In the present era, the plastic waste problem is a global challenge due to its massive production. The post-use of waste plastic influences the earth's environment, human life, marine life, and ocean. Thus there is a ... -
On h-local functions in ideal topological spaces
(Publishing House of the Romanian Academy, 2023)In this research we introduce h-local functions by using h-open sets in an ideal topological space (X, τ, I). Some properties and characterizations of h-local functions are studied. Also, we introduce and research the ... -
Caristi-type nonunique fixed-point results and fixed-circle problem on bv(s)-metric spaces
(World Scientific Publishing Co., 2023)Fixed-point theory has been comprehensively studied with several methods. One of these methods is to generalize the used metric space such as bv(s)-metric spaces. Another method is to analyze the geometric features of the ... -
On the fixed circle problem on metric spaces and related results
(MDPI, 2023)The fixed-circle issue is a geometric technique that is connected to the study of geometric characteristics of certain points, and that are fixed by the self-mapping of either the metric space or of the generalized space. ... -
