Fei He

摘要:

研究了完备无边界黎曼流形上双调和热方程的整体解。在里奇曲率下界和单位球不坍缩的假设下,给出了双调和热核的指数衰减估计.并证明了Cauchy问题的一个唯一性准则。作为推论,我们证明了双调和热核的守恒律和有界初始数据的整体解的一致L-无限估计。

英文摘要:

We study entire solutions of the biharmonic heat equation on complete Riemannian manifolds without boundary. We provide exponential decay estimates for the biharmonic heat kernel under assumptions on the lower bound of Ricci curvature and noncollapsing of unit balls. And we prove a uniqueness criteria for the Cauchy problem. As corollaries we prove the conservation law for the biharmonic heat kernel and a uniform L-infinite estimate for entire solutions starting with bounded initial data.
