Homogeneous Plane Waves
Matthias Blau, Martin O'Loughlin
Motivated by the search for potentially exactly solvable time-dependent string backgrounds, we determine all homogeneous plane wave (HPW) metrics in any dimension and find one fami…
On the Boundary Dynamics of Chern-Simons Gravity
Giovanni Arcioni, Matthias Blau, Martin O'Loughlin
We study Chern-Simons theory with a complex G_C or a real G x G gauge group on a manifold with boundary - this includes Lorentzian and Euclidean (anti-) de Sitter (E/A)dS gravity f…
Penrose limits, supergravity and brane dynamics
Matthias Blau, José Figueroa-O'Farrill, George Papadopoulos
We investigate the Penrose limits of classical string and M-theory backgrounds. We prove that the number of (super)symmetries of a supergravity background never decreases in the li…
Penrose limits and maximal supersymmetry
Matthias Blau, Jose Figueroa-O'Farrill, Christopher Hull +1
We show that the maximally supersymmetric pp-waves of IIB superstring and M-theories can be obtained as a Penrose limit of the supersymmetric AdS x S solutions. In addition we find…
