Towards the theory of fuzzy differential equations

Fuzzy Sets and Systems, 2002
Here, the authors consider a comparative analysis of alternative approaches found in the existing literature, the common point of these approaches being the fact that they all avoid the use of fuzzy derivatives. Moreover, the authors devote to three new ideas in the theory of such ``derivativeless'' fuzzy differential equations. Namely, they define the

Fuzzy differential equations and the extension principle

Information Sciences, 2007
In this paper, the authors study the Cauchy problem for differential equations, considering its parameters and initial conditions given by fuzzy sets. They prove that a solution for fuzzy differential equations can be obtained through Zadeh's extension principle and they also prove the existence of a fuzzy solution which is strongly dependent on the ...

Viability theory and fuzzy differential equations

Fuzzy Sets and Systems, 2005
The authors present a new viability theory for differential inclusions and establish new existence results for fuzzy differential equations. In the literature, viability theory is presented for first-order differential inclusions where the nonlinearity is bounded.

Carathéodory solutions of fuzzy differential equations

Fuzzy Sets and Systems, 2002
Here, the authors establish a solution to fuzzy differential equations with right-hand side satisfying a Carathéodory condition. They do not quote important references, e.g. results due to \textit{V. Lakshmikantham} and \textit{Ram N. Mohapatra} [Fuzzy sets and fuzzy differential equations. K.
