Causal dynamical triangulation for non-critical open-closed string field theory
AbstractWe extend the 2 dimensional Causal Dynamical Triangulation (CDT) model from the usual model of closed string to the one of open-closed string. The matrix-vector model describing the loop gas model is modified so as to possess the nature of the CDT, i.e. the time foliation structure. Stochastic quantization method produces interactions of loop and line variables similar to those in the non-critical open-closed string field theories. By taking an appropriate scaling, we realize an extended model of the generalized CDT (GCDT), which keeps the causality in a broad sense

Algebraic Structure in 0<c<1 Open-Closed String Field Theories
We apply stochastic quantization method to Kostov's matrix-vector models for
the second quantization of orientable strings with Chan-Paton like factors,
including both open and closed strings. The Fokker-Planck hamiltonian deduces
an orientable open-closed string field theory at the double scaling limit.
There appears an algebraic structure in the continuum F-P hamiltonian including
a Virasoro algebra and a SU(r) current algebra.Comment: LaTeX 9 page
