On open-closed extension of boundary string field theory
Akira Ishida, Shunsuke Teraguchi
We investigate a classical open-closed string field theory whose open string sector is given by boundary string field theory. The open-closed interaction is introduced by the overl…
A Field-Theoretic Approach to Connes' Gauge Theory on
Hiromi Kase, Katsusada Morita, Yoshitaka Okumura
Connes' gauge theory on is reformulated in the Lagrangian level. It is pointed out that the field strength in Connes' gauge theory is not unique. We explicitly cons…
Lagrangian Formulation of Connes' Gauge Theory
Hiromi Kase, Katsusada Morita, Yoshitaka Okumura
It is shown that Connes' generalized gauge field in non-commutative geometry is derived by simply requiring that Dirac lagrangian be invariant under local transformations of the un…
Gauge Theories Coupled to Fermions in Generation
Hiromi Kase, Katsusada Morita, Yoshitaka Okumura
Gauge theories coupled to fermions in generation are reformulated in a modified version of extended differential geometry with the symbol . After discussing several toy models,…
