World-Sheet Formulation of M Theory
نویسنده
چکیده
We first review the interpretation of world-sheet defects as D branes described by a critical theory in 11 dimensions, that we interpret asM theory. We then show thatD-brane recoil induces dynamically an anti-de-Sitter (AdS) space-time background, with criticality restored by a twelfth time-like dimension described by a Liouville field. Local physics in the bulk of this AdS11 may be described by an Osp(1|32, R) ⊗ Osp(1|32, R) topological gauge theory (TGT), with non-local boundary states in doubleton representations. We draw analogies with structures previously exhibited in two-dimensional black-hole models. Wilson loops of ‘matter’ in the TGT may be described by an effective string action, and defect condensation may yield string tension and cause a space-time metric to appear.

World Sheet Logarithmic CFT in AdS Strings, Ghost-Matter Mixing and M-theory
We discuss several closely related concepts in the NSR formulation of superstring theory. We demonstrated that recently proposed NSR model for superstrings on AdS5×S 5 is described by the world-sheet logarithmic conformal field theory (LCFT). The origin of LCFT on a world-sheet is closely connected to the matter-ghost mixing in the structure of a brane-like vortex operators. We suggest a dynami...
متن کاملFinite Size Analysis of the U ( 1 ) Phase Transition using the World - sheet Formulation
We present a high statistics analysis of the pure gauge compact U(1) lattice theory using the the world−sheet or Lagrangian loop representation. We have applied a simulation method that deals directly with (gauge invariant) integer variables on plaquettes. As a result we get a significant amelioration of the simulation that allows to work with large lattices avoiding the metaestability problems...
متن کاملComplex World - Sheets from N = 2 Strings
We study some properties of target space strings constructed from (2,1) heterotic strings. We argue that world-sheet complexification is a general property of the bosonic sector of such target world-sheets. We give a target space interpretation of this fact and relate it to the non-gaussian nature of free String Field Theory. We provide several one loop calculations supporting the stringy const...

متن کاملTopological String on AdS 3 ×N
We study the topologically twisted string theory on the general back-ground AdS3× N which is compatible with the world-sheet N = 2 superconformal symmetry and is extensively discussed in the recent works [20]. After summarizing the algebraic structure of the world-sheet topological theory, we show that the space-time (boundary) conformal theory should be also topological. We directly construct ...
