Abstract:

Using the renormalization group method, we got the effective asymptotic expansion of the exact solution of a class of singular perturbation problems for third order semilinear equations, and several examples were given to explain the validity of our result.

Key words: renormalization group method; singular perturbation; effective asymptotic expansion
