We review various aspects of configurations of intersecting branes, including the conditions
for preservation of supersymmetry. In particular, we discuss the projection conditions on the …

We investigate the supersymmetric D-brane configurations in the pp-wave backgrounds
proposed by Maldacena and Maoz. We study the surviving supersymmetry in a D-brane …

We derive intersecting brane solutions in pp-wave spacetime by solving the supergravity
field equations explicitly. The general intersection rules are presented. We also generalize …

We consider D-branes of open superstrings in the AdS5× S5 background. The possible
configurations of D-branes preserving half of supersymmetries are classified by analyzing …

Departing from the observation that the Penrose limit of AdS 3× S 3 is a group contraction in
the sense of Inönü and Wigner, we explore the relation between the symmetric D-branes of …

The cubic interaction vertex and the dynamical supercharges are constructed for open
strings ending on D7-branes, in light-cone superstring field theory in PP-wave background …

We find classical solutions of D-branes in pp-wave spacetime with nonconstant NS–NS flux.
We also present Dp–Dp′ bound state solutions in this background. We further analyze the …

We analyse the existence of closed timelike curves in spacetimes which possess an
isometry. In particular we check which discrete quotients of such spaces lead to closed …

In this paper, we present several gravitational wave solutions in A d S 5× S 5 string
backgrounds, as well as in A d S 7× S 4 and A d S 4× S 7 backgrounds in M theory …

A class of Dp and Dp-D (p+ 4)-brane solutions are constructed in the Penrose limit of the
linear-dilaton geometry. The classical solutions are shown to break all space-time …
