In the paper we study boundary-value and spectral problems for the Laplacian operator in a domain with a smooth boundary. It is assumed that on a small part of the boundary there is a Dirichlet boundary condition and on all the rest boundary there is a Steklov condition. We study the behaviour of the initial problem when a small parameter defining the size of the Dirichlet parts of the boundary tends to zero.

具有快速交替Steklov边界条件的椭圆问题的算子估计

在本文中,我们研究具有光滑边界的拉普拉斯算子的边值问题和谱问题。假定在边界的一小部分上有Dirichlet边界条件,在所有其余边界上有Steklov条件。当定义边界Dirichlet部分大小的小参数趋于零时,我们研究初始问题的行为。
