Abstract

Boundary value problem B1x = f with an abstract linear operator B1, corresponding to an Fredholm integro-differential equation with ordinary or partial differential operator is researched. An exact solution to B1x = f in the case when a bijective operator B1 has a factorization of the form B1 =BB0 where B and B0 are two linear more simple than B1 second degree abstract operators, received. Conditions for factorization of the operator B1 and a criterion for bijectivity of B1 are found.

将抽象算子分解为两个二阶算子及其在积分微分方程中的应用
研究了具有抽象线性算子 B1 的边界值问题 B1x = f,它与具有常微分或偏微分算子的弗雷德霍姆积分微分方程相对应。在双射算子 B1 具有 B1 =BB0 形式的因式分解(其中 B 和 B0 是两个比 B1 更简单的二阶线性抽象算子)的情况下,得到了 B1x = f 的精确解。找到了算子 B1 因式分解的条件和 B1 的双射性准则。
