Noncommutativity in linear dilaton background

by Ip Bhattacharyya, Alok Kumar, Swapna Mahapatra , 2001
"... We consider quantization of open string theories in linear dilaton and constant antisymmetric tensor backgrounds and discuss the noncommutativity of space-time coordinates arising in such theories, including their relationship with light-like noncommutativity as well as backgrounds with null isometr ..."

"... Abstract: In this paper we will study tachyon effective action for Dp-brane in bosonic string theory in the linear dilaton background. We obtain the tachyon effective Lagrangian from boundary state coeficient of Dp-brane in the linear dilaton background and compare it with tachyon effective Lagrangi ..."

Rolling tachyon with electromagnetic field in linear dilaton background,” hep-th/0312149

by Kenji Nagami
"... Rolling tachyon in linear dilaton background is examined by using an effective field theory with gauge field on an unstable D-brane in bosonic string theory. Several solutions are identified with tachyon matter equipped with constant electromagnetic field in linear dilaton background. The time evolu ..."

Linear Dilaton Background and Fully Localized Intersecting Five-branes

by Kazutoshi Ohta, Takashi Yokono , 2000
"... We investigate a near-horizon geometry of NS5-branes wrapping on a Riemann surface, which asymptotically approaches to linear dilaton backgrounds. We concretely find a fully localized solution of the near-horizon geometry of intersecting NS5-branes. We also discuss a relation to a description of Lan ..."

Phases of quantum gravity in AdS(3) and linear dilaton backgrounds

by A. Giveon, D. Kutasov, E. Rabinovici, A. Sever - 2005) [arXiv:hep-th/0503121]. – 37 – K. Gawedzki, “Noncompact WZW conformal field theories,” arXiv:hep-th/9110076
"... We show that string theory in AdS3 has two distinct phases depending on the radius of curvature RAdS = √ kls. For k> 1 (i.e. RAdS> ls), the SL(2,C) invariant vacuum of the spacetime conformal field theory is normalizable, the high energy density of states is given by the Cardy formula with ce ..."

arXiv:YYMM.NNNN Discrete States in Light-Like Linear Dilaton Background

by Pei-ming Ho, Sheng-yu Darren Shih , 711
"... We study the spectrum of bosonic strings in the light-like linear dilaton background and find discrete states. These are physical states which exist only at specific values of momentum. All except one discrete states generate spacetime symmetries. The exceptional discrete state corresponds to constr ..."

The string theory on AdS3 as a marginal deformation of a linear dilaton background,” Nucl

by Gaston Giribet - Phys. B
"... We investigate N-point string scattering amplitudes in AdS3 space. Based on recent observations on the solutions of KZ and BPZ-type differential equations, we discuss how to describe the string theory in AdS3 as a marginal deformation of a (flat) linear dilaton background. This representation resemb ..."

by Miao Li , 1995
"... Dirichlet-branes have emerged as important objects in studying nonperturbative string theory. It is important to generalize these objects to more general backgrounds other than the usual flat background. The simplest case is the linear dilaton condensate.
