Query: Hidden Symmetries and Integrability in Higher Dimensional Rotating Black
  Hole Spacetimes   This is a short pedagogical introduction to the subject of Killing-Stackel
and Killing-Yano tensors and their role in the integrability of various types
of equations that are of physical interest in curved spacetime, the main
application being higher dimensional rotating black holes with cosmological
constant.
