$c=1$ strings as a matrix integral

We study the perturbative S S -matrix of the c=1 c = 1 string and show that it admits a description in terms of a double-scaled (0+0)-dimensional matrix integral based on the spectral curve \mathsf{x}(z) = 2\sqrt{2}\cos(z) 𝗑 ( z ) = 2 2 cos ⁡ ( z ) , \mathsf{y}(z)=\sin(z) 𝗒 ( z )...
