1 String as a Topological Model
The discrete states in the c = 1 string are shown to be the physical states of a certain topological sigma model. We define a set of new fields directly from c = 1 variables, in terms of which the BRST charge and energy-momentum tensor are rewritten as those of the topological sigma model. Remarkably, ground ring generator x turns out to be a coordinate of the sigma model. All of the discrete s...
متن کاملTopological field theory interpretations and LG representation of c = 1 string theory
We analyze the topological nature of c = 1 string theory at the self–dual radius. We find that it admits two distinct topological field theory structures characterized by two different puncture operators. We show it first in the unperturbed theory in which the only parameter is the cosmological constant, then in the presence of any infinitesimal tachyonic perturbation. We also discuss in detail...
متن کاملOn Physical States in c < 1 String Theory On Physical States in c < 1 String Theory
The BRST cohomology analysis of Lian and Zuckerman leads to physical states at all ghost number for c < 1 matter coupled to Liouville gravity. We show how these states are related to states at ghost numbers zero(pure vertex operator states – DK states) and ghost number one(ring elements) by means of descent equations. These descent equations follow from the double cohomology of the String BRST ...
متن کاملTwo – matrix model and c = 1 string theory
We show that the most general two–matrix model with bilinear coupling underlies c = 1 string theory. More precisely we prove that W 1+∞ constraints, a subset of the correlation functions and the integrable hierarchy characterizing such two– matrix model, correspond exactly to the W 1+∞ constraints, to the discrete tachyon correlation functions and to the integrable hierarchy of the c = 1 string...
متن کاملTopological Amplitudes in String Theory
We show that certain type II string amplitudes at genus g are given by the topologi-cal partition function F g discussed recently by Bershadsky, Cecotti, Ooguri and Vafa. These amplitudes give rise to a term in the four-dimensional effective action of the form g F g W 2g , where W is the chiral superfield of N = 2 supergravitational multi-plet. The holomorphic anomaly of F g is related to non-l...
