AbstractIn this article, we carry out the convergence analysis of a recently proposed dual--mixed hybridized finite volume scheme for the numerical approximation of transport problems in symmetrizable form. Optimal error estimates are obtained for the scalar unknown and the flux in the appropriate graph norm, the superconvergence of the hybrid variable and of its post-processed (nonconforming) reconstruction are proved. Numerical experiments are included to support the theoretical conclusions.
