摘要

本文研究的是\({\mathbb {R}}^{n+1}\) 上的一类可变系数三阶偏微分算子，其子类包含在任意空间维度上的一些 KdV 型可变系数算子。对于这样的类以及邻接类，我们得到了卡勒曼估计和在\({\mathbb {R}}^{n+1}\) 任意点的局部可解性。我们还讨论了在分散方程中的可能应用。

Carleman estimates for third order operators of KdV and non KdV-type and applications

In this paper we study a class of variable coefficient third order partial differential operators on \({\mathbb {R}}^{n+1}\), containing, as a subclass, some variable coefficient operators of KdV-type in any space dimension. For such a class, as well as for the adjoint class, we obtain a Carleman estimate and the local solvability at any point of \({\mathbb {R}}^{n+1}\). A discussion of possible applications in the context of dispersive equations is provided.

期刊介绍： This journal, the oldest scientific periodical in Italy, was originally edited by Barnaba Tortolini and Francesco Brioschi and has appeared since 1850. Nowadays it is managed by a nonprofit organization, the Fondazione Annali di Matematica Pura ed Applicata, c.o. Dipartimento di Matematica "U. Dini", viale Morgagni 67A, 50134 Firenze, Italy, e-mail annali@math.unifi.it). A board of Italian university professors governs the Fondazione and appoints the editors of the journal, whose responsibility it is to supervise the refereeing process. The names of governors and editors appear on the front page of each issue. Their addresses appear in the title pages of each issue.
