چکیده
Fuzzy differential and integral equations have been studied by many authors [1, 2, 5, 6, 7, 14]. Kaleva [5] discussed the properties of differentiable fuzzy set-valued mappings by means of the concept of H-differentiability introduced by Puri and Ralescu [9]. Seikkala [11] defined the fuzzy derivative which is a generalization of the Hukuhara derivative [9] and the fuzzy integral which is the same as that proposed by Dubois and Prade [3, 4]. Balachandran and Dauer [1] established the existence of solutions of perturbed fuzzy integral equations. Subrahmanyam and Sudarsanam [13] studied fuzzy Volterra integral equations. Park and Jeong [8] proved the existence and uniqueness of solutions of fuzzy Volterra-Fredholm integral equations of the form

On existence and uniqueness of solutions of a nonlinear Volterra-Fredholm integral equation
In this paper we investigate the existence and uniqueness for Volterra-Fredholm type integral equations and extension of this type of integral equations. The result is obtained by using the coupled fixed point theorems in the framework of Banach space $ X=C([a,b],mathbb{R})$. Finally, we give an example to illustrate the applications of our results.

متن کاملTheorems of Existence and Uniqueness for Nonlinear Fredholm and Volterra Integral Equations for Functions with Values in L-spaces
We consider nonlinear integral equations of Fredholm and Volterra type with respect to functions having values in L-spaces. Such class of equations includes set-valued integral equations, fuzzy integral equations and many others. We prove theorems of existence and uniqueness of the solutions for such equations and investigate data dependence of their solutions.
