Abstract
In the paper estimates are established on the solution of systems of first-order differential equations
subject to two-point conditions of the form
which enable us, in particular, to obtain an estimate of the order of uniform convergence of the method of lines for solving periodic boundary-value problems for second-order nonlinear parabolic partial differential equations of form
For problems with boundary conditions containing the derivatives
where the functions
satisfy, in a small neighborhood of the solutionu(t,x) being examined of Eq. (3), the inequalities
, for which the approximation is only of the first order relative to the net steph, the uniform convergence of the approximate solutions to the exact one is established to the second order relative toh.
