Set-valued collectively compact operators and applications to set-valued differential equations

Computing, 1979
Recent theorems on sequences of collectively compact operators which approximate the operator of a given fixed point problem are generalized to set-valued operators. By means of these theorems, not only an easy access to some recent results with respect to the numerical treatment of set-valued initial value problems (p. e.

Set-valued nonlinear contractive operators in PM-spaces

2021
In this paper, we consider some nonlinear contraction for set-valued operators and prove some fixed point results in the case of set-valued operators are ordered-close and not ordered-close, and in the case of set-valued operators are UCAV (LCAV) in quasi-ordered $PM$-spaces.

Torque-Bounded Admittance Control With Implicit Euler Realization of Set-Valued Operators

IEEE/ASME transactions on mechatronics
When a robot collides with environments of unknown stiffness, the resultant torque saturation can cause the conventional admittance control to exhibit unsafe behaviors such as large resilience force, oscillation, and snapping back.

On Nemytskii operator for set-valued functions

Publicationes Mathematicae Debrecen, 1999
The author presents generalizations (in some sense) of her previous results that appeared in [Publ. Math. 54, No. 1-2, 33-37 (1999; Zbl 0921.47056)]. In fact, here she treats the problem of characterizing those vector-valued, or set-valued functions that generate such a Nemytskij operator which maps a \(\text{lip}^2\) space (space of functions with ...

Linguistic set-valued decision making based on LWA operator

2010 IEEE International Conference on Industrial Engineering and Engineering Management, 2010
In linguistic group decision analysis, we need to solve group decision making with uncertain linguistic information. By analyzing many illustrative example, we notice that not all of linguistic values of the initial linguistic expression domain are used to evaluate decision making problem.

Algorithms for complex interval‐valued q‐rung orthopair fuzzy sets in decision making based on aggregation operators, AHP, and TOPSIS

Expert Syst. J. Knowl. Eng., 2020
The interval‐valued q‐rung orthopair fuzzy set (IVq‐ROFS) and complex fuzzy set (CFS) are two generalizations of the fuzzy set (FS) to cope with uncertain information in real decision making problems. The aim of the present work is to develop the concept

Set-valued extension of operators via Steiner selections (I)—Theoretical results

Applied Mathematics and Mechanics, 2002
A way to extend operators in spaces of continuous functions to spaces of continuous set-valued functions is obtained by the authors. This extension is developed through the Steiner selections of set-valued functions. Properties and characteristics of the convergence of sequences of operators of this class are studied.

On the Convergence of Discretizations for Set Valued Operator Equations

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1997
AbstractThis paper is concerned with the theory of the convergence of discretizations for set‐valued operator equations. It is a continuation of investigations in [2], [7], [5], some results for one‐valued operators have been generalized herein. As an application, two examples for set‐valued differential equations are discussed.

Decision making based on interval-valued complex single-valued neutrosophic hesitant fuzzy generalized hybrid weighted averaging operators

Journal of Intelligent & Fuzzy Systems, 2020
The interval complex single-valued neutrosophic fuzzy set (ICSVNFS) and hesitant fuzzy set (HFS) are two important different generalizations of the fuzzy set (FS) to cope with unreliable and unpredictable information in the real world.

Complex Interval-valued Intuitionistic Fuzzy Sets and their Aggregation Operators

Fundamenta Informaticae, 2019
The objective of this manuscript is to present the concept of the complex interval-valued intuitionistic fuzzy (CIVIF) set, their algebraic operations and their corresponding aggregation operators, which can better represent the time-periodic problems ...
