An application of weakly contractive mappings to boundary value problems of interval-valued functions (Q2877988)

The authors studies a boundary value problem of the form NEWLINE\[NEWLINE\begin{aligned} &X^\prime(t)= F(t, X(t)) ,\;\; t\in [0,T],\\ & X(0)=X(T),\end{aligned} NEWLINE\]NEWLINE where \(X:[0,T] \to 2^{\mathbb{R}}\) is an interval-valued map. Here, \(X^\prime\) denotes the derivative of \(X\) in the sense of Hukuhara.
