The purpose of this paper is to propose methods for verifying the positivity of a weak solution u of an elliptic problem assuming H 0 1-error estimation‖ u− u ˆ‖ H 0 1≤ ρ given some numerical approximation u ˆ and an explicit error bound ρ. We provide a sufficient condition for the solution to be positive and analyze the range of application of our method for elliptic problems with polynomial nonlinearities. We present numerical examples where our method is applied to some important problems.
