Abstract: This paper establishes the convergence of adaptive mixed finite element methods for second-order
linear non-selfadjoint indefinite elliptic problems in three dimensions with piecewise Lipschitz continuous
coefficients. The error is measured in the L^2 norm of the flux variable and then allows for an adaptive
algorithm with collective Dörfler marking. The axioms of adaptivity apply to this setting and guarantee the
rate optimality for Raviart-Thomas and Brezzi-Douglas-Marini finite elements of any order for sufficiently small initial mesh-sizes and bulk parameter.
