- Let $Ω_1$, $Ω_2$ be two domains in $\mathbb{C}^n$ with Kobayashi metrics $k_{Ω_i}$ and consider $f \in \mathcal{O}(Ω_1,Ω_2)$ a holomorphic mapping. Let $\mathfrak{F}_1$ and $\mathfrak{F}_2$ be a family of geodesics defined on $Ω_1$ and $Ω_2$ respectively, where a geodesic between $z$ and $w$ in $Ω_i$ is the length minimizing curve between the two points for the metric $k_{Ω_i}$. We say that a holomorphic function \textit{preserves geodesics} if for any geodesic $γ_1$ in $\mathfrak{F}_1$ its image is a subset of a geodesic $γ_2$ in $\mathfrak{F}_2$ ($f(γ_1)\subset γ_2$). We aim to characterise the family of such functions between families of Kobayashi geodesics passing through a point in the unit disc $\mathbb{D}$ and in the unit ball $\mathbb{B}^n$. Some additional results in the complex plane $\mathbb{C}$ and $\mathbb{C}^n$.
