Query: A priori and a posteriori error estimation for finite element
  approximation of advection-diffusion-reaction equation with spatially
  variable coefficients   This paper presents a study of finite element error estimation of
advection-diffusion-reaction equation with spatially variable coefficients. We
have derived a priori and a posteriori errors in both energy and L2 norm. We
have used residual-based a posteriori error estimator. Numerical results are
also presented to verify our theoretical approach.
