Abstract
In this paper the scalar equation ut + f(u) = 0 is approximated by three-point difference schemes in conservation form with an order of accuracy p equal to one or two. The partial differential equations approximated by the schemes with (p + 1)-th order accuracy are derived and their schock structures are analytically obtained and found to be close to the numerical shock profiles. By using these results, correction terms are proposed for second order schemes.
