The Cauchy problem for the modified Kawahara equation in Sobolev spaces with low regularity
نویسندگان
چکیده
This paper is concerned with the Cauchy problem of the modified Kawahara equation. By using the Fourier restriction norm method introduced by Bourgain, and using the I-method as well as the L 2 conservation law, we prove that the modified Kawahara equation is globally well-posed for the initial data in the Sobolev space H s (R) with s > − 3 22 .

Low regularity solution of a 5th-order KdV equation
The Kawahara and modified Kawahara equations are fifth-order KdV type equations and have been derived to model many physical phenomena such as gravitycapillary waves and magneto-sound propagation in plasmas. This paper establishes the local well-posedness of the initial-value problem for Kawahara equation in H(R) with s > − 4 and the local well-posedness for the modified Kawahara equation in H(...

متن کاملThe low regularity global solutions for the critical generalized KdV equation
We prove that the Cauchy problem of the mass-critical generalized KdV equation is globally well-posed in Sobolev spaces Hs(R) for s > 6/13; we require that the mass is strictly less than that of the ground state in the focusing case. The main approach is the “I-method” together with some multilinear correction analysis. The result improves the previous works of Fonseca, Linares, Ponce (2003) an...

متن کاملNon-regularity in Hölder and Sobolev spaces of solutions to the semilinear heat and Schrödinger equations
In this paper we study the Cauchy problem for the semilinear heat and Schrödinger equations, with the nonlinear term f(u) = λ|u|αu. We show that low regularity of f (i.e., α > 0 but small) limits the regularity of any possible solution for a certain class of smooth initial data. We employ two different methods, which yield two different types of results. On the one hand, we consider the semilin...
