Abstract
We present two a-posteriori error estimators for elliptic partial diff
erential equations, when we use a mixed method. One is based on a adeq
uate evaluation of the residual of the finite element solution and the
other on the solution of a local problem. We prove their equivalence
with the norm of the error, when the data is locally smooth.
