Conformal invariants of curves via those for inscribed polygons with circular edges
Harald Dorn
The conformal nature of smooth curves in is characterised by conformal length, curvature and torsion. We present a derivation of these conformal parameters via a lim…
Non-Abelian gauge field dynamics on matrix D-branes in curved space and two-dimensional -models
H. Dorn
A survey is given of the formulation of a -model describing an open string moving in general target space background fields and coupling to both a matrix-valued D-brane position…
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…
Analysis of All Dimensionful Parameters Relevant in Gravitational Dressing of Conformal Theories
H. Dorn, H. -J. Otto
Starting from a covariant and background independent definition of normal ordered vertex operators we give an alternative derivation of the KPZ relation between conformal dimension…
