摘 要: 反向热传导问题是一类严重不适定问题.可以用Fourier正则化方法去稳定近似一个反向热传导问题.Fourier正则化的优点是简单而有效.一个Holder型稳定性误差估计被得到. Backward heat conduction problems (BHCP) are a class of severely ill-posed problem. In this paper, we use the Fourier regularization method to stabilize a backward heat conduction problem. The advantage of the Fourier regularization method lies in its simplicity and effectiveness. A Hoelder stability error estimate for the problem is obtained.
