Existence and Uniqueness of Tri-tronqu\'ee Solutions of the second   Painlev\'e hierarchy
  The first five classical Painlev\'e equations are known to have solutions described by divergent asymptotic power series near infinity. Here we prove that such solutions also exist for the infinite hierarchy of equations associated with the second Painlev\'e equation. Moreover we prove that these are unique in certain sectors near infinity.
