Query: Analytic approximation in $L^p$ and coinvariant subspaces of the Hardy
  space   We generalize a classical result by A.Macintyre and W.Rogosinski on best
$H^p$--approximation in $L^p$ of rational functions. For each inner function
$\theta$ we give a description of $H^p$--badly approximable functions in $\bar
\theta H^p$.
