一类抛物型Monge-Ampere方程解的极限

Limits of Solutions to a Parabolic Monge-Ampere Equation

John Loftin, Mao-Pei Tsui

摘要:

我们从偏微分方程的角度给出了在仿射空间中非紧凸超曲面上的仿射法线流的结果,强调了所涉及的估计。我们的结果涉及$S^n$上抛物型Monge-Ampere方程解的极限,其中光滑严格凸初值函数序列单调增加到极限初值函数,该极限初值函数在$S^n$的至少一个半球上是无穷的.我们证明了长时间的存在性和瞬时平滑相当一般的初始数据,我们的特点是古老的解决方案作为椭球或抛物面。我们必须使用安德鲁斯和古铁雷斯黄,由于卡拉比和障碍的估计。

英文摘要:

We present the results from our earlier paper (arXiv:math/0602484) on the affine normal flow on noncompact convex hypersurfaces in affine space from a more PDE point of view, emphasizing the estimates involved. Our results concern the limits of solutions to a parabolic Monge-Ampere equation on $S^n$, where a sequence of smooth strictly convex initial value functions increase monotonically to a limiting initial value function which is infinite on at least a hemisphere of $S^n$. We prove long-time existence and instantaneous smoothing for quite general initial data, and we characterize ancient solutions as ellipsoids or paraboloids. We make essential use of estimates of Andrews and Gutierrez-Huang, and barriers due to Calabi.
