Abstract:In this work we prove an Aubin-Nitsche Lemma for a positivity-preserving discretisation of an elliptic
problem. Due to the nonlinearity of the discretisation, the result requires as a first step
the proposal of a linearised adjoint problem that can be linked to the method of
choice by appropriately selecting weights. This linearised adjoint problem, together
with a regularity result, allow the proof of an optimal-order error estimate in the $L^2$-norm of
the error.
