Let $U=S^{1}\times\mathbb{R}^{2}$ and let $V$ be a Green’s function with exactly one pole on $S^{1}\times\{0\}$. In [GW00] $V$ is constructed by passing to the universal cover $\widetilde{U}=\mathbb{R}^{3}$, where the lifted function $\widetilde{V}$ is a periodic Green’s function constructed using a Weierstrass series. $V$ is only positive in a certain bounded open set in $U$. The corresponding hyperkähler metric on this bounded open set is called the Ooguri-Vafa metric. With one particular choice of a compatible complex structure, $\mathfrak{M}$ becomes a holomorphic elliptic fibration over a disc $\mathbb{D}\subset\mathbb{R}^{2}=\mathbb{C}$, and the singular fiber has monodromy of type $I_{1}$. The Ooguri-Vafa metric plays a crucial role in the work of Gross-Wilson [GW00] on collapsing Calabi-Yau metrics on elliptic $\K 3$ surfaces with exactly 24 singular fibers of type $I_{1}$.
