This research note shows subtree isomorphism is in DLOG, and hence NC 2 , for nested trees. To our knowledge this result provides the rst interesting class of trees for which the problem is in a non-randomized version of NC. We also show that one can determine whether or not an arbitrary tree is a nested tree in DLOG.
