W ∞ Structures of 2 D String Theory
ثبت نشده
چکیده
The Ward identities of the W ∞ symmetry in 2D string theory in the tachyon background are studied in the continuum approach. Comparing the solutions with the matrix model results, it is verified that 2D string amplitudes are different from the matrix model amplitudes only by the external leg factors even in higher genus. This talk is based on the recent work [1] and also [2] for the c M < 1 model.

Strange quark matter attached to string cloud in general scalar tensor theory of gravitation
Bianchi type-VI0 space time with strange quark matter attached to string cloud in Nordtvedt [1] general scalar tensor theory of gravitation with the help of a special case proposed by Schwinger [2] is obtained. The field equations have been solved by using the anisotropy feature of the universe in the Bianchi type-VI0 space time. Some important features of the model, thus obtained, have been di...

A geometric interpretation of quantum self–interacting string field theory is given. Relations between various approaches to the second quantization of an interacting string are described in terms of the geometric quantization. An algorythm to construct a quantum nonperturbative interacting string field theory in the quantum group formalism is proposed. Problems of a metric background (in)depen...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملSpacetime Quantization from Non-abelian D-particle Dynamics
We describe the short-distance properties of the spacetime of a system of D-particles by viewing their matrix-valued coordinates as coupling constants of a deformed worldsheet σ-model. We show that the Zamolodchikov metric on the associated moduli space naturally encodes properties of the non-abelian dynamics, and from this we derive new spacetime uncertainty relations directly from the quantum...
متن کاملNon - critical string field theory for 2 d quantum gravity coupled to ( p , q ) – conformal fields
Non-critical string field theory for 2d quantum gravity coupled to (p,q)–conformal fields Abstract We propose a non-critical string field theory for 2d quantum gravity coupled to (p,q) conformal fields. The Hamiltonian is described by the generators of the W p algebra, and the Schwinger-Dyson equation is equivalent to a vacuum condition imposed on the generators of W p algebra.
