We investigate the Penrose limit of various brane solutions including Dp-branes, NS5-branes, fundamental strings, (p,q) fivebranes and (p,q) strings. We obtain special null geodesics with the fixed radial coordinate (critical radius), along which the Penrose limit gives string theories with constant mass. We also study string theories with time-dependent mass, which arise from the Penrose limit of the brane backgrounds. We examine equations of motion of the strings in the asymptotic flat region… 

SEMICLASSICAL STRING SOLUTIONS ON DEFORMED NS5-BRANE BACKGROUNDS AND NEW PLANE WAVE

We study different Penrose limits of supergravity solution of NS5-brane in the presence of RR field. Although in the case of NS5-brane we get a four-dimensional plane wave, in the case with RR field

More on Penrose limits and non-local theories

We obtain the Penrose limit of six dimensional Non-Commutative Open String (NCOS6) theory and show that in the neighborhood of a particular null geodesic it leads to an exactly solvable string theory

Penrose limits and Green–Schwarz strings

We discuss the Green–Schwarz action for type IIB strings in general plane-wave backgrounds obtained as Penrose limits from any IIB supergravity solutions with vanishing background fermions. Using the

On (non)integrability of classical strings in p-brane backgrounds

We investigate the question of possible integrability of classical string motion in curved p-brane backgrounds. For example, the D3-brane metric interpolates between the flat and the AdS5 × S5

Penrose limit and NCYM theories in diverse dimensions

We obtain the Penrose limit of NCYM theories in dimensions 3 ≤ d ≤ 6 which originate from (D(p−2), Dp) supergravity bound state configurations for 2 ≤ p ≤ 5 in the so-called NCYM limit. In most cases

Power-law singularities in string theory and M-theory

We extend the definition of the Szekeres–Iyer power-law singularities to supergravity, string and M-theory backgrounds, and find that are characterized by Kasner-type exponents. The near singularity

Power-law singularities in string theory and M-theory

We extend the definition of the Szekeres–Iyer power-law singularities to supergravity, string and M-theory backgrounds, and find that are characterized by Kasner-type exponents. The near singularity

Penrose limits and spacetime singularities

We give a covariant characterization of the Penrose plane wave limit: the plane wave profile matrix A(u) is the restriction of the null geodesic deviation matrix (curvature tensor) of the original

Penrose limits, supergravity and brane dynamics

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 limit. We classify

Penrose Limits and Non-local theories

We investigate Penrose limits of two classes of non-local theories, little string theories and non-commutative gauge theories. Penrose limits of the near-horizon geometry of NS5-branes help to shed

Supergravity and The Large N Limit of Theories With Sixteen Supercharges

We consider field theories with sixteen supersymmetries, which include U(N) Yang-Mills theories in various dimensions, and argue that their large N limit is related to certain supergravity solutions.

Branes in Time-Dependent Backgrounds and AdS/CFT Correspondence

We study supergravity solutions of Dp-branes in the time-dependent orbifold background. We show that worldvolume theories decouple from the bulk gravity for p less than six. Along AdS/CFT

Penrose Limits and RG Flows

The Penrose-Guven limit simplifies a given supergravity solution into a pp-wave background. Aiming at clarifying its relation to renormalization group flow we study the Penrose-Guven limit of

PP-waves from Nonlocal Theories

We study the Penrose limit of ODp theory. There are two different PP-wave limits of the theory. One of them is a ten dimensional PP-wave and the other a four dimensional one. We observe the later one
