Abstract
For solving the first generalized periodic boundary-value problem in the case of a second-order quasilinear parabolic equation of form
with periodic condition
and boundary conditions
there is examined a longitudinal variant of the method of lines, reducing the solving of problem (1)–(3) to the solving of a two-point problem for a system ofN -1 first-order ordinary differential equations of form
with the two-point conditions
An error estimate is established. The convergence of the solutions of problem (4)–(5) to the generalized solution of problem (1)–(3) is established for two methods of choosing the functions
. Convergence with orderh 2 is guaranteed under the assumption of square-integrability of the third derivative
of the solution of problem (1)–(3).
