Multi-instantons in 2d string theory

Sergei Alexandrov, Rishabh Kaushik

Instanton contributions in 2d string theory are known to include subtle numerical factors $I^¶_{n}$ closely related to a contour prescription in multi-instanton string amplitudes. Bot…

$c = 1$ , $R = 1$ and $N ≫ 1$ : ZZ instantons in 2D String Theory and Matrix Integrals

Rishabh Kaushik

We explore the non-perturbative aspects of $c = 1$ string with compactified Euclidean time, its $0 + 0$ dimensional matrix model duals (at self-dual radius), and $0 + 1$ dimensional Matr…
