| Abstract:
|
In this paper we investigate the existence and uniquness of intuitionistic fuzzy solution for three-point boundary value problem for fractional differential equation:
[math]\displaystyle{ \left\{ \begin{array}{lrr}
D^{\alpha}X(t)=F(t, X_t, D^{\beta}X(t)) & t\in J:=[0, 1]\\
X(t)=\phi(t)&t\in[-r, 0]\\
X(1)=X(\xi)&
\end{array}, \right.
}[/math]
where [math]\displaystyle{ D^{\alpha}, D^{\beta} }[/math] are the standard Riemann--Liouville fractional derivatives (α−β>0) and (1<α < 2), [math]\displaystyle{ (\xi\in[0, 1[) }[/math],[math]\displaystyle{ F:J \times C_0\times\mathbf{IF}^1 \longrightarrow \mathbf{IF}^1 }[/math] is an intuitionistic fuzzy function, [math]\displaystyle{ \phi\in C_0 }[/math], [math]\displaystyle{ \phi(0)=0_{IF} }[/math] and [math]\displaystyle{ C_0=C\left([-r, 0], IF^1\right) }[/math]. We denote by [math]\displaystyle{ X_t }[/math] the element of [math]\displaystyle{ C_0 }[/math] defined by [math]\displaystyle{ X_t(\theta)=X(t+\theta) }[/math], [math]\displaystyle{ \theta\in[-r, 0]. }[/math]
