Objectives:
Recently our group (with collaborators in Halifax, Canada and Cambridge, UK) has developed a generalization of various fundamental tools of four-dimensional (D=4) general relativity to higher dimensions (Petrov classification, Newman-Penrose and GHP formalisms). In this project we plan to apply these methods to various research problems . i) We will study D>4 Einstein spacetimes , their asymptotic properties and generalization of the Goldberg-Sachs theorem for D>5 and construct exact algebraically special D>4 spacetimes. ii) Following our recent work in quadratic gravity, we plan to find various classes of exact algebraically special vacuum solutions of Lovelock gravity. iii) Recently a duality between solutions of incompressible Navier-Stokes equations in p+1 dimensions with vacuum solutions of Einstein equations in p+2 dimensions (which seem to be algebraically special for p=2 ) has been discussed by Strominger et al. We intend to use our D>4 algebraic classification to study duality between solutions of 3+1 Navier-Stokes equations and 4+1 spacetimes.
