Query: The complexity of approximating a trembling hand perfect equilibrium of
  a multi-player game in strategic form   We consider the task of computing an approximation of a trembling hand
perfect equilibrium for an n-player game in strategic form, n >= 3. We show
that this task is complete for the complexity class FIXP_a. In particular, the
task is polynomial time equivalent to the task of computing an approximation of
a Nash equilibrium in strategic form games with three (or more) players.
