Research output: Chapter in Book/Report/Conference proceedingConference contribution


We consider the large time asymptotic behavior of solutions to the Cauchy problem for the modified Korteweg - de Vries equation ut + a(t) (u3)x + 1/3Uxxx = O,(t,r) ϵR x R, with initial data u(0,z) = q1(z),z ϵ R.. We assume that the coefficient a(t) ϵ C1(R) is real, bounded and slowly varying function, such that /a'(t)≤C(l + /t/)-7/6. We suppose that the iriitial dah are real ~ valued and small enough, belonging to the weighted Sobolev space. We prove the time decay estimates of the solutims.We also fiud the asympt,otics for large time of the solution in the neighborhood of the self-similar solution.
