洞域上迹不等式极值的最优化问题

Optimization problem for extremals of the trace inequality in domains with holes

L. M. Del Pezzo

摘要:

本文研究了定义在有界区域$Ø$中且在子集$A.$中为零的函数的Sobolev迹常数,得到了Sobolev迹关于空穴的一阶变分的公式.作为这个公式的结果,我们证明了当$Ø$是一个中心球,对称孔是关键的,当我们考虑变形,保持体积,但不是最佳的某些情况下。

英文摘要:

We study the Sobolev trace constant for functions defined in a bounded domain $Ø$ that vanish in the subset $A.$ We find a formula for the first variation of the Sobolev trace with respect to hole. As a consequence of this formula, we prove that when $Ø$ is a centered ball, the symmetric hole is critical when we consider deformation that preserve volume but is not optimal for some case.
