abstract = {<p style="text-align: justify;">In this paper, we present an a posteriori error estimates of semilinear
quadratic constrained optimal control problems using triangular mixed finite element
methods. The state and co-state are approximated by the order $k\leq 1$ Raviart-
Thomas mixed finite element spaces and the control is approximated by piecewise
constant element. We derive a posteriori error estimates for the coupled state and
control approximations. A numerical example is presented in confirmation of the
theory.</p>},
