Fourier and Tikhonov regularization methods for solving a class of backward heat conduction problems. (Chinese. English summary) Zbl 1150.35591
Summary: A class of one-dimensional backward heat conduction problems are discussed and a Fourier regularization approximating solution with Hölder type stability estimate is given. Moreover, by improving the a priori assumption, a Tikhonov regularization approximating solution with logarithmic type stability estimate is also given and the convergence of the solution at $$t=0$$ is proved.
