In this paper, we study the planar -Minkowski problem(0.1) for all , which was introduced by Lutwak [21]. A detailed exploration of (0.1) on solvability will be presented. More precisely, we will prove that for , there exists a positive function such that (0.1) admits a nonnegative solution vanishes somewhere on . In case , a surprising a-priori upper/lower bound for solution was established, which implies the existence of positive classical solution to each positive function . When , the existence of some special positive classical solution has already been known using the Blaschke-Santalo inequality [7]. Upon the final case , we show that there exist some positive functions such that (0.1) admits no solution. Our results clarify and improve largely the planar version of Chou-Wang's existence theorem [7] for . At the end of this paper, some new uniqueness results will also be shown.

关于平面L p -Minkowski问题
在本文中,我们研究平面 -Minkowski问题(0.1) 对全部 ,这是由Lutwak [21]提出的。将介绍(0.1)关于可溶性的详细说明。更确切地说,我们将证明,有一个积极的作用 使得(0.1)承认非负解消失在 。以防万一,建立了令人惊讶的先验上/下界解,这意味着每个正函数都存在正经典解。什么时候,已经使用Blaschke-Santalo不等式[7]知道了一些特殊的正经典解的存在。在最后的情况下,我们发现这里存在一些积极的功能 因此(0.1)不接受任何解决方案。我们的结果在很大程度上澄清和改进了Chou-Wang存在定理[7]的平面形式。。在本文的结尾,还将显示一些新的唯一性结果。
