Let $f$ be analytic in the unit disk $\mathbb{D}= \{z \in \mathbb{C}~:~ |z| <1\}$, and $\mathcal{S}$ be the subclass of normalized univalent functions givenby $f(z)=\sum_{n=1}^{\infty}a_{n}z^{n},~a_{1}:=1$ for $z \in\mathbb{D}$. Wepresent the sharp bounds of the third-order Hankel determinant for inversefunctions when it belongs to of the class of Ozaki close-to-convex.
