A modified quasi-reversibility method for inverse source problem of Poisson equation

In this article, we consider an inverse source problem for Poisson equation in a strip domain. That is to determine term the from noisy boundary data. This ill-posed sense of Hadamard, i.e., small changes data can cause arbitrarily large results. Before give main results about our proposed problem, display some useful lemmas at first. Then propose modified quasi-reversibility regularization method deal with and obtain convergence rate by using priori parameter choice rule. Numerical examples are provided show effectiveness method.
