Title: Local and global well-posedness for the 2D generalized Zakharov-Kuznetsov equation
Author: Linare, Felipe
Pastor, Ademir
Abstract: This paper addresses well-posedness issues for the initial value problem (IVP) associated with the generalized Zakharov-Kuznetsov equation, namely, {ut + partial derivative(x)Delta u+ u(k)u(x) = 0, (x, y) is an element of R(2), t > 0, u(x, y, 0) = u(0)(x, y). For 2 <= k <= 7, the IVP above is shown to be locally well posed for data in H(s) (R(2)), s > 3/4. For k >= 8, local well-posedness is shown to hold for data in H(s) (R(2)), s > s(k), where s(k) = 1 - 3/(2k - 4). Furthermore, for k >= 3, if u(0) is an element of H(1) (R(2)) and satisfies parallel to u(0)parallel to(H1) << 1, then the solution is shown to be global in H(1)(R(2)). For k = 2, if u(0) is an element of H(s)(R(2)), s > 53/63, and satisfies parallel to u(0)parallel to(L2) < root 3 parallel to phi parallel to(L2), where phi is the corresponding ground state solution, then the solution is shown to be global in H(s)(R(2)).
