In this paper, we analyze a residual-type a posteriori error estimator of the finite volume element method for a quasi-linear elliptic problem of nonmonotone type and derive computable upper and lower bounds on the error in the H1-norm. Numerical experiments are provided to illustrate the performance of the proposed estimator.
