The Phase Diagram of Fluid Random Surfaces with Extrinsic Curvature
We present the results of a large-scale simulation of a Dynamically
Triangulated Random Surface with extrinsic curvature embedded in
three-dimensional flat space. We measure a variety of local observables and use
a finite size scaling analysis to characterize as much as possible the regime
of crossover from crumpled to smooth surfaces.Comment: 29 pages. There are also 19 figures available from the authors but

Solutions of the Knizhnik - Zamolodchikov Equation with Rational Isospins and the Reduction to the Minimal Models
In the spirit of the quantum Hamiltonian reduction we establish a relation
between the chiral -point functions, as well as the equations governing
them, of the WZNW conformal theory and the corresponding Virasoro
minimal models. The WZNW correlators are described as solutions of the Knizhnik
- Zamolodchikov equations with rational levels and isospins. The technical tool
exploited are certain relations in twisted cohomology. The results extend to
arbitrary level and isospin values of the type , $ \
2j, 2j' \in Z\!\!\!Z_+$.Comment: 40 page
