Query: Eigenvalue Estimates for the Dirac Operator on Quaternionic Kaehler
  Manifolds   We consider the Dirac operator on compact quaternionic Kaehler manifolds and
prove a lower bound for the spectrum. This estimate is sharp since it is the
first eigenvalue of the Dirac operator on the quaternionic projective space.
