Nonlocal Representation of the $sl(2,R)$ Algebra for the Chazy equation

Andronikos Paliathanasis, Sameerah Jamal, P. G. L. Leach

英文摘要:

A demonstration of how the point symmetries of the Chazy Equation become nonlocal symmetries for the reduced equation is discussed. Moreover we construct an equivalent third-order differential equation which is related to the Chazy Equation under a generalized transformation, and find the point symmetries of the Chazy Equation are generalized symmetries for the new equation. With the use of singularity analysis and a simple coordinate transformation we construct a solution for the Chazy Equation which is given by a Right Painlevé Series. The singularity analysis is applied to the new third-order equation and we find that it admits two solutions, one given by a Left Painlevé Series and one given by a Right Painlevé Series where the leading-order behaviors and the resonances are explicitly those of the Chazy Equation.
