Conditional stability in determining a heat source. (English) Zbl 1081.35136

Summary: We establish the uniqueness and conditional stability in determining a heat source term from boundary measurements which are started after some time. The key is analyticity of solutions in the time and we apply the maximum principle for analytic functions.
