Stability estimate for the heat equation backward in time with Neumann and integral boundary conditionsIn this paper, we first prove that the heat equation backward in time with Neumann and integral boundary conditions is an ill-posed problem. Then, we establish a stability estimate of Hölder type for... Author: Duc Duc Van Keyword: The heat equation backward in time stability estimate ill-posed problem.
