USp ( 2 k ) Matrix Model : Schwinger - Dyson Equations and Closed - Open String Interactions
نویسنده
چکیده
We derive the Schwinger-Dyson/loop equations for the USp(2k) matrix model which close among the closed and open Wilson loop variables. These loop equations exhibit a complete set of the joining and splitting interactions required for the nonorientable TypeI superstrings. The open loops realize the SO(2nf ) Chan-Paton factor and their linearized loop equations derive the mixed Dirichlet/Neumann boundary conditions.

Integrability of Schwinger-Dyson Equations in 2D Quantum Gravity and c < 1 Non-critical String Field Theory
We investigate the integrability of the Schwinger-Dyson equations in c = 1 − 6 m(m+1) string field theory which were proposed by Ikehara et al as the continuum limit of the Schwinger-Dyson equations of the matrix chain model. We show the continuum Schwinger-Dyson equations generate a closed algebra. This algebra contains Virasoro algebra but does not coincide with W∞ algebra. We include in the ...
متن کاملString field theory in the temporal gauge.
We construct the string eld Hamiltonian for c = 1 6 m(m+1) string theory in the temporal gauge. In order to do so, we rst examine the Schwinger-Dyson equations of the matrix chain models and propose the continuum version of them. Results of boundary conformal eld theory are useful in making a connection between the discrete and continuum pictures. The W constraints are derived from the continuu...
متن کاملJa n 19 95 LOOP SPACE HAMILTONIAN FOR c ≤ 1 OPEN STRINGS
We construct a string field Hamiltonian describing the dynamics of open and closed strings with effective target-space dimension c ≤ 1. In order to do so, we first derive the Dyson-Schwinger equations for the underlying large N vector+matrix model and formulate them as a set of constraints satisfying decoupled Virasoro and U(1) current algebras. The Hamiltonian consists of a bulk and a boundary...
متن کاملn-Hermitian Matrix model
We derive the loop equations for the d-dimensional n-Hermitian matrix model. These are a consequence of the Schwinger-Dyson equations of the model. Moreover we show that in leading order of large N the loop equations form a closed set. In particular we derive the loop equations for the n = 2 matrix model recently proposed to describe the coupling of Two-dimensional quantum gravity to conformal ...
متن کاملCombinatorial Solution of the Two-Matrix Model
We write down and solve a closed set of Schwinger-Dyson equations for the twomatrix model in the large N limit. Our elementary method yields exact solutions for correlation functions involving angular degrees of freedom whose calculation was impossible with previously known techniques. The result sustains the hope that more complicated matrix models important for lattice string theory and QCD m...
