Algorithmic method for deriving Lax pairs from the invariant Painlevé analysis of nonlinear partial differential equations

Journal of Mathematical Physics, 1991
Given a partial differential equation, its Painlevé analysis will first be performed with a built-in invariance under the homographic group acting on the singular manifold function. Then, assuming an order for the underlying Lax pair, a multicomponent pseudopotential of projective Riccati type, the components of which are homographically invariant, is ...

A higher-order difference method for 3-D parabolic partial differential equations with nonlinear first derivative terms

International Journal of Computer Mathematics, 1991
In this paper, we present a finite difference method of 0(k 2 +kh 2+h 4) for the second order nonlinear 3-D parabolic partial differential equation v 1 u xx + v 2 U yy +v 3 u zz = f(x,y,z,t,u,u x ,u y ,u z ,u t ) where v i , i=l, 2, 3 are positive constants, using 19 spatial grid points subject to Dirichlet boundary conditions.

A nonlinear second-order partial differential equation derived from a linear type-II integral equation with quadratic dispersion

Journal of Physics A: Mathematical and General, 1990
A relation between a type-II linear integral equation with quadratic dispersion and a second-order nonlinear partial differential equation is demonstrated. A limiting process in the spectral parameter space sets the analysis somewhat apart from the usual type of analysis.

On oblique derivative problems for fully nonlinear second-order elliptic partial differential equations on nonsmooth domains

Nonlinear Analysis: Theory, Methods & Applications, 1990
The fully nonlinear elliptic \(PDE\) \(F(x,u,Du,D^ 2u)=0\) in \(\Omega\) with the oblique derivative condition \(\partial u/\partial\gamma+f(x,u)=0\) on \(\partial\Omega\) is known to have unique solutions in domains \(\Omega\) that are sufficiently smooth, see \textit{P. L. Lions} [Duke Math. J.
