Topological Field Theory Interpretations and LG Representation of c=1 String Theory
L. Bonora, C. S. Xiong
We analyze the topological nature of string theory at the self--dual radius. We find that it admits two distinct topological field theory structures characterized by two diff…
Exact Correlators of Two-Matrix Models
L. Bonora, C. P. Constantinidis, C. S. Xiong
We compute exact solutions of two--matrix models, i.e. detailed genus by genus expressions for the correlation functions of these theories, calculated without any approximation. We…
Correlation functions of two-matrix models
L. Bonora, C. S. Xiong
We show how to calculate correlation functions of two matrix models. Our method consists in making full use of the integrable hierarchies and their reductions, which were shown in…
Multi-field representations of KP hierarchies and multi-matrix models
L. Bonora, C. S. Xiong
We discuss the integrable hierarchies that appear in multi--matrix models. They can be envisaged as multi--field representations of the KP hierarchy. We then study the possible red…
The generalized KP hierarchy
C. S. Xiong
We propose one possible generalization of the KP hierarchy, which possesses multi bi--hamiltonian structures, and can be viewed as several KP hierarchies coupled together.
Matrix models without scaling limit
L. Bonora, C. S. Xiong
In the context of hermitean one--matrix models we show that the emergence of the NLS hierarchy and of its reduction, the KdV hierarchy, is an exact result of the lattice characteri…
