چکیده

We consider the M(2, 3) Minimal Liouville gravity, whose states in the gravity sector are represented by irreducible modules of the Virasoro algebra. We present a recursive construction for BRST cohomology classes. This construction is based on using an explicit form of singular vectors in irreducible modules of the Virasoro algebra. We construct an algebra of operators acting on the BRST cohomology space. The operator algebra of physical states is established by use of these operators.

Electronic effects at 2 and 7 α–position of divalent unsaturated seven membered ring R2C6H6M (M=C, Si, Ge, Sn, Pb)

Electronic effects were investigated on the singlet–triplet energy gaps of divalent unsaturated seven- membered ring R2C6H6M (M=C, Si, Ge, Sn, Pb, R= –H, -CH3, i-Pr , t-Bu) at B3LYP/6-311++G** level. All the triplet states of R2C6H6C were more stable than the related the singlet states while all the singlet states of R2C6H6M (M= Si, Ge, Sn, Pb, R= –H, -CH3, i-Pr , t-Bu) were more stable than th...

On 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 ...

So(2,c) Invariant Ring Structure of Brst Cohomology and Singular Vectors in 2d Gravity with C < 1 Matter

We consider BRST quantized 2D gravity coupled to conformal matter with arbitrary central charge c M = c(p, q) < 1 in the conformal gauge. We apply a Lian-Zuckerman SO(2, C I) ((p, q)-dependent) rotation to Witten's c M = 1 chiral ground ring. We show that the ring structure generated by the (relative BRST cohomology) discrete states in the (matter ⊗ Liouville ⊗ ghosts) Fock module may be obtain...

On the Liouville Approach to Correlation Functions for 2-D Quantum Gravity

We evaluate the three point function for arbitrary states in bosonic minimal models on the sphere coupled to quantum gravity in two dimensions. The validity of the formal continuation in the number of Liouville screening charge insertions is shown directly from the Liouville functional integral using semi-classical methods. ⋆ Work supported in part by the National Science Foundation grant PHY–8...
