The effect of interpolating the coefficients in nonlinear parabolic Galerkin procedures
The effect of interpolating the coefficients in nonlinear parabolic Galerkin procedures
Error estimates are derived for a class of Galerkin methods for a quasilinear parabolic equation. In these Galerkin methods, both continuous and discrete in time, the nonlinear coefficient in the differential equation is interpolated into a finite-dimensional function space in order to compute the integrals involved. Asymptotic error estimates of …
