Integrability of differential equations with fluid mechanics application: from Painleve property to the method of simplest equation
Zlatinka I. Dimitrova, Kaloyan N. Vitanov
We present a brief overview of integrability of nonlinear ordinary and partial differential equations with a focus on the Painleve property: an ODE of second order has the Painleve…
