We show that Halphen's second quadratic system can be described by monodromy evolving deformations. Our result is a generalization of the work on the DH-V system by Chakravarty and Ablowitz.9 pagesClassical Analysis and ODEsMathematical Physics34M55; 17A99Quadratic equations and monodromy evolving deformationstext
