The heterotic perturbative vacua in string geometry theory
Koichi Nagasaki, Matsuo Sato
String geometry theory is one of the candidates of the non-perturbative formulation of superstring theory. In this paper, in string geometry theory, we identify perturbative hetero…
Fundamental structure of string geometry theory
Matsuo Sato
String geometry theory is one of the candidates of a non-perturbative formulation of string theory. In this theory, the ``classical'' action is almost uniquely determined by T-symm…
String geometry phenomenology
Matsuo Sato, Maki Takeuchi
Recently, a potential for string backgrounds is obtained from string geometry theory, which is a candidate for the non-perturbative formulation of string theory. By substituting a…
String Geometry Theory and The String Vacuum
Matsuo Sato
String geometry theory is a candidate of the non-perturvative formulation of string theory. In this theory, strings constitute not only particles but also the space-time. In this r…
Gauge invariant discretization of Chern-Simons couplings
Kohta Hatakeyama, Matsuo Sato, Gota Tanaka
We discretize Chern-Simons couplings in gauge invariant way. We obtain (p+q)-forms representing Chern-Simons couplings on (p + q)-simplexes from wedge products of p- and q-forms on…
