Chazy equation

From Wikipedia, the free encyclopedia

In mathematics, the Chazy equation is the differential equation

It was introduced by Jean Chazy (1909, 1911) as an example of a third-order differential equation with a movable singularity that is a natural boundary for its solutions.

One solution is given by the Eisenstein series

Acting on this solution by the group SL2 gives a 3-parameter family of solutions.
