Abstract

In this paper, we consider a biharmonic problem with Steklov-type boundary conditions on one part of the boundary and with the Farwig condition on the other part. For this problem, questions of uniqueness of solutions are studied, and in the case of non-uniqueness, provided that the weighted Dirichlet integral is bounded, the exact number of linear independent solutions to the problem under consideration is established. Using the variational principle, uniqueness (non-uniqueness) theorems are obtained, as well as exact formulas for calculating the dimension of the space of solutions depending on the value of the parameter included in the weighted Dirichlet integral.

利用斯特克洛夫型和 Farwig 边界条件求解双谐波问题

摘要在本文中，我们考虑了一个双谐波问题，其边界的一部分具有 Steklov 型边界条件，另一部分具有 Farwig 条件。对于这个问题，研究了解的唯一性问题，在非唯一性情况下，只要加权 Dirichlet 积分是有界的，就可以确定所考虑问题的线性独立解的精确数目。利用变分原理，可以得到唯一性（非唯一性）定理，以及计算解空间维度的精确公式，这取决于加权狄利克特积分中包含的参数值。
