SUMMARY:WANDs in higher-dimensional gravity - Mark Durkee\, DAMTP

DESCRIPTION:In 4 dimensions\, the Petrov classification and Newman-Penrose
  formalism have for many years proved a useful tool in studying various as
 pects of general relativity\, for example in the construction of the Kerr 
 solution\, and the study of linearized perturbations.  In recent years\, a
  higher-dimensional version has been developed by Coley\, Milson\, Pravda 
 and Pravdova (CMPP) and others\, based around so-called Weyl-Aligned Null 
 Directions (WANDs).  The usefulness of this for practical calculations is 
 not yet entirely clear.  This talk will give an introduction to the CMPP f
 ormalism\, discuss some possible applications\, before describing some rec
 ent results on the geodesity of WANDs in arbitrary dimension.\narXiv:0908.
