Scattering of Long Folded Strings and Mixed Correlators in the Two-Matrix Model
J. -E. Bourgine, K. Hosomichi, I. Kostov +1
We study the interactions of Maldacena's long folded strings in two-dimensional string theory. We find the amplitude for a state containing two long folded strings to come and go b…
Strong coupling limit of Bethe Ansatz equations
Ivan Kostov, Didina Serban, Dmytro Volin
We develop a method to analyze the strong coupling limit of the Bethe ansatz equations supposed to give the spectrum of anomalous dimensions of the planar gauge theory…
Boundary Loop Models and 2D Quantum Gravity
Ivan Kostov
We study the O(n) loop model on a dynamically triangulated disk, with a new type of boundary conditions, discovered recently by Jacobsen and Saleur. The partition function of the m…
Boundary Ground Ring and Disc Correlation Functions in Liouville Quantum Gravity
Ivan K. Kostov
We construct the boundary ground ring in c < 1 open string theories with non-zero boundary cosmological constant (FZZT brane), using the Coulomb gas representation. The ring relati…
Conformal Field Theory Techniques in Random Matrix models
Ivan K. Kostov
In these notes we explain how the CFT description of random matrix models can be used to perform actual calculations. Our basic example is the hermitian matrix model, reformulated…
Generalized Hirota Equations in Models of 2D Quantum Gravity
Jorge Alfaro, Ivan Kostov
We derive a set of bilinear functional equations of Hirota type for the partition functions of the related integrable statistical models defined on a random lattice. These…
