摘要 考虑一类非齐次热方程的侧边值问题,这是一类严重不适定问题.首先给出该问题的解,然后用分数次Tikhonov正则化方法给出其近似解,并进行误差估计. A class of inhomogeneous sideways heat equation is discussed,and its solution is given for the first time,which is a serious ill-posed problem.In this paper,the approximate solution of the problem is given by using the fractional Tikhonov regularization method,and the error estimates are obtained.
