The D0-brane metric in N = 2 sigma models
Thomas Wynter
We investigate the physical metric seen by a D0-brane probe in the background geometry of an N=2 sigma model. The metric is evaluated by calculating the Zamolodchikov metric for th…

Advances in Large N Group Theory and the Solution of Two-Dimensional R^2 Gravity
V. A. Kazakov, M. Staudacher, T. Wynter
We review the recent exact solution of a matrix model which interpolates between flat and random lattices. The importance of the results is twofold: Firstly, we have developed a ne…
