Boundary Value Problems for a Class of First-Order Fuzzy Delay Differential Equations
In this paper, we study a class of fuzzy differential equations with variable boundary value conditions. Applying the upper and lower solutions method and the monotone iterative technique, we provide some sufficient conditions for the existence of solutions, which can be applied to discuss some dyna...
