Cauchy Problem for for some high order generalization of Korteweg - de Vries equation

Z. A. Sobirov, S. Abdinazarov

In this work we study Cauchy problem for a high-order differential equation $\frac{\partial u(y,x)}{\partial y}+P(\frac{\partial}{\partial x})u(y,x)=γ\frac{\partial}{\partial x}(u^…
