Ooguri–Vafa metric

In differential geometry, the Ooguri–Vafa metric is a four-dimensional Hyperkähler metric. The Ooguri–Vafa metric is named after Hirosi Ooguri and Cumrun Vafa, who first described it in 1996 using the Gibbons–Hawking ansatz. Another construction was given by Davide Gaiotto, Gregory Moore and Andrew Neitzke in 2008.
