Field Equations of Massless Fields in the New Interpretation of the Matrix Model
Ko Furuta, Masanori Hanada, Hikaru Kawai +1
Recently, some of the authors have introduced a new interpretation of matrix models in which covariant derivatives on any curved space can be expressed by large-N matrices. It has…
Non-local Matching Condition and Scale-invariant Spectrum in Bouncing Cosmology
Chong-Sun Chu, Ko Furuta, Feng-Li Lin
In cosmological scenarios such as the pre-big bang scenario or the ekpyrotic scenario, a matching condition between the metric perturbations in the pre-big bang phase and those in…
Locality, Causality and Noncommutative Geometry
Chong-Sun Chu, Ko Furuta, Takeo Inami
We analyse the causality condition in noncommutative field theory and show that the nonlocality of noncommutative interaction leads to a modification of the light cone to the light…
Topics in Nonlinear Sigma Models in D=3
Ko Furuta, Takeo Inami, Masayoshi Yamamoto
Nonlinear sigma models (NLSM) in d=3 have many interesting and non-trivial features, which were explored poorly in contrast with NLSM in d=2 and d=4. We present a few results from…
