Open/closed duality for FZZT branes in c=1
Ian Ellwood, Akikazu Hashimoto

TL;DR
This paper explores the relationship between FZZT branes and matrix integrals in the c=1 string theory, revealing how certain matrix models emerge from brane partition functions and discussing related subtleties.
Contribution
It demonstrates how the matrix integral of Imbimbo and Mukhi arises from the FZZT partition function in the double-scaled c=1 matrix model, extending to 0A and commenting on 0B.
Findings
Matrix integral of Imbimbo and Mukhi derived from FZZT partition function
Similar results shown for 0A string theory
Comments on subtleties in 0B case
Abstract
We describe how the matrix integral of Imbimbo and Mukhi arises from a limit of the FZZT partition function in the double-scaled c=1 matrix model. We show a similar result for 0A and comment on subtleties in 0B.
