In this letter, to fit the character of solutions to impulsive boundary value problems (IBVPs), we firstly construct a piecewise continuous space using the reproducing kernel function (RKF) of smooth reproducing kernel Hilbert space (RKHS) . Then we present a fourth order convergent collocation approach for IBVPs by using the piecewise continuous basis functions yielded by RKFs in . Also, the convergence order of our approach is proved. The accuracy and convergence order are shown numerically.

一种求解脉冲边值问题的核函数算法
在这封信中,为了适应脉冲边值问题(IBVPs)解的特点,我们首先使用平滑再生核希尔伯特空间(RKHS)的再生核函数(RKF)构造一个分段连续空间。. 然后,我们通过使用 RKF 产生的分段连续基函数,提出了 IBVP 的四阶收敛配置方法. 此外,证明了我们方法的收敛顺序。精度和收敛顺序以数字形式显示。
