#### A Lax pair for the (1+3) nonlinear equation

... and physics. The discovery of inverse scattering method played an important role in reconsidering the place of integrable systems of nonlinear partial differential equations in mathematical sciences. The search for a systematic approach to developing **exact** **solutions** of such systems has become one of the main problems in the theory of integrable systems.

#### One method for constructing **exact** **solutions** of equations of two-dimensional hydrodynamics of an incompressible fluid

We propose a simple algebraic method for constructing **exact** **solutions** of equations of two-dimensional hydrodynamics of an incompressible fluids.The problem reduces to consecutively **solution** three linear partial differential equations for a nonviscous fluid and to solving three linear partial differential equations ...
