摘要
本文应用算子理论讨论了迁移理论中出现的一类带控制参数的积分微分方程,在具有物理意义的假设下,对齐次和非齐次两种情形,给出了方程具有非零非负解的充分条件.
In this paper,using the operator theory,we analyse the integral differential equation with a control parameter arising in the transport theory. Under some assumptions having physical meaning,we give some sufficient conditions of the existence of non-zero and nonnegative solutions for homo- geneous and inhomogensous equations.
