Jiuyi Zhu

摘要:

研究了双拉普拉斯方程解的加倍不等式和节点集。本文在Logan关于Laplace本征函数节点集的最新发展的基础上,得到了解的节点集及其梯度的多项式上界。此外,我们推导出节点解集的隐式上界。给出了双拉普拉斯方程解的两类加倍不等式。因此,给出了解的消失率。

英文摘要:

We investigate the doubling inequality and nodal sets for the solutions of bi-Laplace equations. A polynomial upper bound for the nodal sets of solutions and their gradient is obtained based on the recent development of nodal sets for Laplace eigenfunctions by Logunov. In addition, we derive an implicit upper bound for the nodal sets of solutions. We show two types of doubling inequalities for the solutions of bi-Laplace equations. As a consequence, the rate of vanishing is given for the solutions.
