LINEAR FIRST-ORDER FUZZY DIFFERENTIAL EQUATIONS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2006
We give the expression for the solution to some particular initial value problems in the space E1 of fuzzy subsets of ℝ. We deduce some interesting properties of the diameter and the midpoint of the solution and compare the solutions with the corresponding ones in the crisp case.

Fuzzy Partial Differential Equations

2002
We begin this chapter with discussing the type of elementary fuzzy partial differential equation we wish to solve. As in Chapter 3, 4, 7 and 8 we then consider types of solutions. If one fuzzifies the crisp partial differential equation and then solves, you are attempting to get the classical solution . is the topic of the second section.

Fuzzy Fractional Differential Equations

2020
Different materials and processes in many applied sciences like electrical circuits, biology, biomechanics, electrochemistry, electromagnetic processes and, others are widely recognized to be well predicted by using fractional differential operators in accordance with their memory and hereditary properties.

Nonlocal Intuitionistic Fuzzy Differential Equation

2020
In this paper, we shall prove the existence and uniqueness theorem of solution of intuitionistic fuzzy differential equation with nonlocal condition by using the contraction mapping principle and we establish some property of the solution like the continuous dependence.

Fuzzy stochastic differential equations of decreasing fuzziness: Approximate solutions

Journal of Intelligent & Fuzzy Systems, 2015
Abstract We consider recently introduced fuzzy stochastic differential equations with solutions of decreasing fuzziness. In general, such the equations do not have solutions that could be written in explicit, closed form. Therefore some methods of construction of approximate solutions are proposed in this paper.

On the fuzzy differential equations

Soft Computing in Intelligent Systems and Information Processing. Proceedings of the 1996 Asian Fuzzy Systems Symposium, 2002
It is well-known that, in the research on fuzzy differential equations, O. Kaleva's (1987, 1990) work is important. In this paper, we develop his work in two directions: (1) the existence and uniqueness theorem for a solution to the Cauchy problem of fuzzy differential equations; and (2) the existence theorem under a compactness-type condition to the ...

Intuitionistic Fuzzy Functional Differential Equations

2017
In this paper, we discuss the local and global existence and uniqueness results for intuitionistic fuzzy functional differential equations. For the local existence and uniqueness we use the method of successive approximations and for global existence and uniqueness we use the contraction principle.
