ERROR ESTIMATES ON A BACKWARD HEAT EQUATION BY A WAVELET DUAL LEAST SQUARES METHOD
Xiangtuan Xiong, Chu‐Li Fu · International Journal of Wavelets Multiresolution and Information Processing · 2007
We apply a wavelet dual least squares method to a backward heat equation. Connecting Shannon wavelet bases with a special project method, the dual least squares method, we can obtain a regularized solution. Meanwhile, a new error estimate between the approximate solution and exact solution is proved.
