On a 'Mysterious' Case of a Quadratic Hamiltonian

Sakovich, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)

We show that one of the five cases of a quadratic Hamiltonian, which were recently selected by Sokolov and Wolf who used the Kovalevskaya-Lyapunov test, fails to pass the Painlevé test for integrability.
On a Whitham-Type Equation

Sakovich, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)

The Hunter-Saxton equation and the Gurevich-Zybin system are considered as two mutually non-equivalent representations of one and the same Whitham-type equation, and all their common solutions are obtained exactly.
On Transformations of the Rabelo Equations

Sakovich, A.; Sakovich, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)

We study four distinct second-order nonlinear equations of Rabelo which describe pseudospherical surfaces. By transforming these equations to the constant-characteristic form we relate them to some well-studied integrable ...
Singularity Analysis and Integrability of a Burgers-Type System of Foursov

Sakovich, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)

We apply the Painlevé test for integrability of partial differential equations to a system of two coupled Burgers-type equations found by Foursov, which was recently shown by Sergyeyev to possess infinitely many commuting ...
