Penrose Limits and Spacetime Singularities
Matthias Blau, Monica Borunda, Martin O'Loughlin +1
We give a covariant characterisation of the Penrose plane wave limit: the plane wave profile matrix is the restriction of the null geodesic deviation matrix (curvature tenso…
The holonomy of IIB supercovariant connection
G. Papadopoulos, D. Tsimpis
We show that the holonomy of the supercovariant connection of IIB supergravity is contained in $SL(32, \bR)$. We also find that the holonomy reduces to a subgroup of $SL(32-N)\st (…
Solvable models of strings in homogeneous plane wave backgrounds
Matthias Blau, Martin O'Loughlin, George Papadopoulos +1
We solve closed string theory in all regular homogeneous plane-wave backgrounds with homogeneous NS three-form field strength and a dilaton. The parameters of the model are constan…
