Properties of the Solution for Investment Model of Fixed Assets with Time Delay
含有时滞的固定资产投资模型解的性质

This paper gives a class of investment model of fixed assets with time delay. The model involves distributed parameter system with non-local and delayed boundary condition. Applying the theory of functional analysis and integral equation, we prove that the solution of the system exists and is unique, and get the analytical expression of the solution; furthermore, we discuss the stability of the solution.
