Explicit metrics for a class of two-dimensional superintegrable systems
Galliano Valent, Christian Duval, Vsevolod Shevchishin
We obtain, in local coordinates, the explicit form of the two-dimensional, super-integrable systems of Matveev and Shevchishin involving cubic integrals. This enables us to determi…
