Time-dependent backgrounds of 2D string theory: Non-perturbative effects
Sergei Yu. Alexandrov, Ivan K. Kostov
We study the non-perturbative corrections (NPC) to the partition function of a compactified 2D string theory in a time-dependent background generated by a tachyon source. The sine-…

Instantons in Non-Critical strings from the Two-Matrix Model
V. Kazakov, I. Kostov
We derive the non-perturbative corrections to the free energy of the two-matrix model in terms of its algebraic curve. The eigenvalue instantons are associated with the vanishing c…

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…
