On Wilson loops and -potentials from the AdS/CFT relation at
H. Dorn, H. -J. Otto
We give a short introduction to and a partial review of the work on the calculation of Wilson loops and -potentials via the conjectured AdS/CFT duality. Included is a disc…
potential from AdS-CFT relation at : Dependence on orientation in internal space and higher curvature corrections
H. Dorn, H. -J. Otto
Within the classical approximation we calculate the static potential via the AdS/CFT relation for nonzero temperature and arbitrary internal orientation of the quarks. We…
Remarks on T-duality for open strings
H. Dorn, H. -J. Otto
This contribution gives in sigma-model language a short review of recent work on T-duality for open strings in the presence of abelian or non-abelian gauge fields. Furthermore, it…
On T-duality for open strings in general abelian and nonabelian gauge field backgrounds
H. Dorn, H. -J. Otto
We discuss T-duality for open strings in general background fields both in the functional integral formulation as well as in the language of canonical transformations. The Dirichle…
Some conclusions for noncritical string theory drawn from two- and three-point functions in the Liouville sector
H. Dorn, H. -J. Otto
Starting from the known expression for the three-point correlation functions for Liouville exponentials with generic real coefficients at we can prove the Liouville equation of mot…
Two and three-point functions in Liouville theory
H. Dorn, H. -J. Otto
Based on our generalization of the Goulian-Li continuation in the power of the 2D cosmological term we construct the two and three-point correlation functions for Liouville exponen…
