摘要
Volterra积分微分方程是近年来学者们研究的重要课题,在物理、生物、激光及人口增长等模型中得到广泛应用。本文对自变量分段连续型Volterra积分微分方程解的唯一性、收敛性、全局和局部超收敛性用配置法进行了研究。
Volterra Integro-differential equation is an important research topic in recent years.It has been widely used in physics,biology,laser and population growth models,and so forth.In this paper,the uniqueness,convergence,global and local superconvergence of the solutions are studied for the type of equations by using the collocation method.
