p-Regularity and p-Regular Modification in ⊤-Convergence Spaces

open access: yesMathematics, 2019
Fuzzy convergence spaces are extensions of convergence spaces. ⊤-convergence spaces are important fuzzy convergence spaces. In this paper, p-regularity (a relative regularity) in ⊤-convergence spaces is discussed by two equivalent approaches. In addition,

Convergence Classes of L-Filters in L,M-Fuzzy Topological Spaces

open access: yesJournal of Mathematics, 2021
An L,M-fuzzy topological convergence structure on a set X is a mapping which defines a degree in M for any L-filter (of crisp degree) on X to be convergent to a molecule in LX.

p-Topologicalness—A Relative Topologicalness in ⊤-Convergence Spaces

open access: yesMathematics, 2019
In this paper, p-topologicalness (a relative topologicalness) in ⊤-convergence spaces are studied through two equivalent approaches. One approach generalizes the Fischer’s diagonal condition, the other approach extends the Gähler’s ...

A NEW APPROACH TO EGOROV’S THEOREM BY MEANS OF 𝛼𝛽-STATISTICAL IDEAL CONVERGENCE

open access: yesПроблемы анализа, 2022
In this work, we introduce the 𝛼𝛽-statistical pointwise ideal convergence, 𝛼𝛽-statistical uniform ideal convergence, and 𝛼𝛽-equi-statistical ideal convergence for sequences of fuzzy-valued functions.

New methods for the estimation of Takagi-Sugeno model based extended Kalman filter and its applications to optimal control for nonlinear systems [PDF]

open access: yes, 2012
This paper describes new approaches to improve the local and global approximation (matching) and modeling capability of Takagi–Sugeno (T-S) fuzzy model. The main aim is obtaining high function approximation accuracy and fast convergence. The main problem

Convergence theorem for fuzzy martingales

open access: yesJournal of Mathematical Analysis and Applications, 1991
Fuzzy-valued measures and their relationship to fuzzy random variables are studied. The concept of conditional expectation for fuzzy random variable is proposed. The authors prove the Radon-Nikodym theorem in this setting and a convergence theorem for fuzzy martingale.

Statistical convergence on L−fuzzy normed space

open access: yesFilomat, 2023
In this paper, we study the concept of statistical convergence on L?fuzzy normed spaces. Then we give a useful characterization for statistically convergent sequences. Furthermore, we illustrate that our method of convergence is more general than the usual convergence on L?fuzzy normed spaces.

On the convergence of sequences in ℝ+ through weighted geometric means via multiplicative calculus and application to intuitionistic fuzzy numbers

open access: yesJournal of Taibah University for Science, 2022
We define weighted geometric mean method of convergence for sequences in [Formula: see text] by using multiplicative calculus and obtain necessary and sufficient conditions under which convergence of sequences in [Formula: see text] follows from ...

Adaptive particle swarm optimization [PDF]

open access: yes, 2009
An adaptive particle swarm optimization (APSO) that features better search efficiency than classical particle swarm optimization (PSO) is presented. More importantly, it can perform a global search over the entire search space with faster convergence ...

Almost uniformly convergence on MV-algebra of intuitionistic fuzzy sets [PDF]

open access: yesNotes on IFS, 2023
The aim of this contribution is to formulate some definitions of almost uniformly convergence for a sequence of observables in the MV-algebra of the intuitionistic fuzzy sets.
