摘要:

本文构建了有限区间上光滑函数空间中一阶常微分方程组的线性非齐次边值问题可解性的一般理论。这类问题采用通用形式的边界条件,涵盖超定与欠定情形,还可包含阶数高于微分方程组阶数的导数项。本研究基于问题的所谓特征矩阵展开,该矩阵的指标与Fredholm数(即问题核与余核的维数)分别与非齐次边值问题的指标和Fredholm数一致。我们还证明了特征矩阵序列的一个极限定理。

英文摘要:

In the paper we develop a general theory of solvability of linear inhomogeneous boundary-value problems for systems of first-order ordinary differential equations in spaces of smooth functions on a finite interval. This problems are set with boundary conditions in generic form, that covers overdetermined and underdetermined cases. They also may contain derivatives, whose orders exceed the order of the differentiall system. Our study is based on using of the so called characteristic matrix of the problem, whose index and Fredholm numbers (i.e., the dimensions of the problem kernel and co-kernel) coincide, respectively, with the index and Fredholm numbers of the inhomogeneous boundary-value problem. We also prove a limit theorems for a sequence of characteristic matrices.
