On 2nd-order fully-nonlinear equations with links to 3rd-order fully-nonlinear equations [PDF]

Open Communications in Nonlinear Mathematical Physics
We derive the general conditions for fully-nonlinear symmetry-integrable second-order evolution equations and their first-order recursion operators. We then apply the established Propositions to find links between a class of fully-nonlinear third-order ...

Equations for nonlinear diffusion

Lietuvos Matematikos Rinkinys, 2010
The diffusion is the result of Brownian movement and occurs with a finite velocity. We presented the nonlinear diffusion equation, with diffusion coefficient directly proportional to the impurities concentration.
