Abstract

The polyharmonic Navier problem is considered, the uniqueness (non-uniqueness) of its solution is studied in unbounded domains under the assumption that the generalized solution of this problem has a finite Dirichlet integral with weight \(|x|^a\). Depending on the values of the parameter \(a\), uniqueness theorems are proved and exact formulas are found for calculating the dimension of the space of solutions of the Navier problem for a polyharmonic equation in the exterior of a compact set and in a half-space.

论无界域多谐方程的纳维问题解法

摘要考虑了多谐 Navier 问题，在该问题的广义解具有权重 \(|x|^a\) 的有限 Dirichlet 积分的假设下，研究了其解在无界域中的唯一性（非唯一性）。根据参数 \(a\) 的值，证明了唯一性定理，并找到了计算紧凑集外部和半空间中多谐方程的纳维叶问题解的空间维数的精确公式。 doi 10.1134/s1061920823040209

期刊介绍： Russian Journal of Mathematical Physics is a peer-reviewed periodical that deals with the full range of topics subsumed by that discipline, which lies at the foundation of much of contemporary science. Thus, in addition to mathematical physics per se, the journal coverage includes, but is not limited to, functional analysis, linear and nonlinear partial differential equations, algebras, quantization, quantum field theory, modern differential and algebraic geometry and topology, representations of Lie groups, calculus of variations, asymptotic methods, random process theory, dynamical systems, and control theory.
