利用Kurzweil广义常微分方程理论,在较弱的条件下,给出一类变系数线性常微分方程有界变差解存在唯一的充要条件及通解公式,并给出了一个应用.
Under weaker conditions,by using Kurzweil generalized ordinary differential equations theory,necessary and sufficient conditions are given for existence and uniqueness of bounded variation solutions for a class of variable-coefficient linear ordinary differential equations,and the general solution formula are obtained.An example is given to show the application of the results.
