We investigate a complex curve in the c = 1 string theory which provides a geometric interpretation for different kinds of D‐branes. The curve is constructed for a theory perturbed by a tachyon potential using its matrix model formulation. The perturbation removes the degeneracy of the non‐perturbed curve and allows to identify its singularities with ZZ branes. Also, using the constructed curve, we find non‐perturbative corrections to the free energy and elucidate their CFT origin.
