Error-constant estimation under the maximum norm for linear Lagrange interpolation

open access: yesJournal of Inequalities and Applications, 2022
For the linear Lagrange interpolation over a triangular domain, we propose an efficient algorithm to rigorously evaluate the interpolation error constant under the maximum norm by using the finite-element method (FEM). In solving the optimization problem

Bounds on supremum norms for Hecke eigenfunctions of quantized cat maps [PDF]

open access: yes, 2006
We study extreme values of desymmetrized eigenfunctions (so called Hecke eigenfunctions) for the quantized cat map, a quantization of a hyperbolic linear map of the torus.

Quasi-homogeneous associative functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
A triangular norm is a special kind of associative function on the closed unit interval [0,1]. Triangular norms (or t-norms) were introduced in the context of probabilistic metric space theory, and they have found applications also in other areas, such ...

Convergence in Fuzzy Semi-Metric Spaces

open access: yesMathematics, 2018
The convergence using the fuzzy semi-metric and dual fuzzy semi-metric is studied in this paper. The infimum type of dual fuzzy semi-metric and the supremum type of dual fuzzy semi-metric are proposed in this paper. Based on these two types of dual fuzzy

Convergence and superconvergence of variational discretization for parabolic bilinear optimization problems

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we investigate a variational discretization approximation of parabolic bilinear optimal control problems with control constraints. For the state and co-state variables, triangular linear finite element and difference methods are used for ...

On α ̌–φ ̆-Fuzzy Contractive Mapping in Fuzzy Normed Space

open access: yesمجلة بغداد للعلوم, 2023
The idea of fixed points represents one of the most potent mathematical tools. This paper's main purpose is to introduce a new kind of fuzzy contractive mapping in a fuzzy normed space (briefly  space) namely "fuzzy contractive mapping".

Ptolemaic Indexing [PDF]

open access: yes, 2015
This paper discusses a new family of bounds for use in similarity search, related to those used in metric indexing, but based on Ptolemy's inequality, rather than the metric axioms. Ptolemy's inequality holds for the well-known Euclidean distance, but is

Probing the chiral magnetic wave with charge-dependent flow measurements in Pb-Pb collisions at the LHC

open access: yesJournal of High Energy Physics, 2023
The Chiral Magnetic Wave (CMW) phenomenon is essential to provide insights into the strong interaction in QCD, the properties of the quark-gluon plasma, and the topological characteristics of the early universe, offering a deeper understanding of ...

Norm-variation of ergodic averages with respect to two commuting transformations

open access: yes, 2017
We study double ergodic averages with respect to two general commuting transformations and establish a sharp quantitative result on their convergence in the norm.
