On fuzzy differential equations

Fuzzy Sets and Systems, 1989
This paper is just an extension of another work by the first author [J. Math. Anal. Appl. 129, 346-361 (1988; Zbl 0645.54009)] where the authors equipped the space of regular fuzzy sets on a Banach space with uniform topology, embedded it into a locally convex topological vector space and then introduced a calculus for fuzzy mappings. Here, the authors

Set differential equations versus fuzzy differential equations

Applied Mathematics and Computation, 2005
The paper is devoted to establish some results on existence, uniqueness and flow invariance for set differential equations, and their connection with fuzzy differential equations. Both types of differential equations are emergent research areas, so the background included in this paper will be appreciated for all people interested in the topic.

Fuzzy Differential Equations

2015
Fuzzy differential equations (FDEs) appear as a natural way to model the propagation of epistemic uncertainty in a dynamical environment. There are several interpretations of a fuzzy differential equation. The first one historically was based on the Hukuhara derivative introduced in Puri-Ralescu [123] and studied in several papers (Wu-Song-Lee [150 ...

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 ...

Numerical solutions of fuzzy differential equations

Fuzzy Sets and Systems, 1999
The authors study the explicit Euler approximation of a Cauchy problem for fuzzy (ordinary) differential equations. By the embedding approach, the original problem in a Banach space with supremum norm is replaced by two parametric, first-order ordinary differential equations. These differential equations can be solved by classical numerical algorithms.

Fuzzy Sets and Fuzzy Differential Equations

2001
Solution of real world problems often rely on solutions of mathematical models of empirical phenomena. It is well known that the precision and exactness necessary during the construction and solution of such models are not always true in real situations.
