“…They also proved GWP for initial data in L 2 (R 2 ). Their result was improved by Isaza et al in [17] where LWP was established for s 1 > − 5 4 and s 2 ≥ 0. The authors also employed the almost conservation machinery of the "I-method" to obtain GWP for s 1 > − 4 7 and s 2 ≥ 0.…”

In this paper we study the fifth order Kadomtsev-Petviashvili II (KP-II) equation on the upper half-plane U = {(x, y) ∈ R 2 : y > 0}. In particular we obtain low regularity local well-posedness using the restricted norm method of Bourgain and the Fourier-Laplace method of solving initial and boundary value problems. Moreover we prove that the nonlinear part of the solution is in a smoother space than the initial data.

“…We may now begin the proof of Theorem 1.2. Since this is a modification of the proof of Isaza, López, and Mejía in [3], we will merely outline the essential steps. To begin, consider the linear problem…”

We show that the fifth-order Kadomtsev-Petviashvili II equation is globally well-posed in an anisotropic Gevrey space, which complements earlier results on the well-posedness of this equation in anisotropic Sobolev spaces. 2010 Mathematics Subject Classification. 35Q35, 35Q53.
“…The Cauchy problem for higher order KP equations has been extensively studied (see [5,13,15,20,26,31,32,33,35,42,43] and references therein). For the IVP associated to (4) see e.g.…”
In this paper we prove the exponential decay of the energy for the high-order Kadomtsev-Petviashvili II equation with localized damping. To do that, we use the classical dissipation-observability method and a unique continuation principle introduced by Bourgain in [3] here extended for the highorder Kadomtsev-Petviashvili. A similar result is also obtained for the twodimensional Zakharov-Kuznetsov (ZK)equation. The method of proof works better for the ZK equation, so we were led to make some subtle modifications on it to include KP type equations. In fact, to reach a key estimate we use an anisotropic Gagliardo-Nirenberg inequality to drop the y-derivative of the norm.
