A note on fuzzy integral equations
Integration of fuzzy mappings was introduced by \textit{D. Dubois} and \textit{H. Prade} [Fuzzy Sets Syst. 8, 105-116 (1982; Zbl 0493.28003)] and generalized by \textit{R. Goetschel jun.} and \textit{W. Voxman} [Fuzzy Sets Syst. 18, 31-43 (1986; Zbl 0626.26014)] using a concept of parametric fuzzy numbers. This paper proves fuzzy versions of existence theorems for certain Volterra and Fredholm integral equations. Another approach to fuzzy integral equations can be found in a paper of \textit{M. Friedman, M. Ming} and \textit{A. Kandel} [Fundam. Inform. 37, No. 1-2, 89-99 (1999; Zbl 0934.45011)].
