Toda Lattice Solutions of Differential-Difference Equations for Dissipative Systems
Yuji Igarashi, Katsumi Itoh, Ken Nakanishi
In a certain class of differential-difference equations for dissipative systems, we show that hyperbolic tangent model is the only the nonlinear system of equations which can admit…
Self-duality in Super D3-brane Action
Yuji Igarashi, Katsumi Itoh, Kiyoshi Kamimura
We establish self-duality of super D3-brane theory as an exact symmetry of the action both in the Lagrangian and Hamiltonian formalism. In the Lagrangian formalism, the action is s…
Electric-Magnetic Duality Rotations and Invariance of Actions
Yuji Igarashi, Katsumi Itoh, Kiyoshi Kamimura
For D=4 theories of a single U(1) gauge field strength coupled to gravity and matters, we show that the electric-magnetic duality can be formulated as an invariance of the actions.…
Canonical Equivalence between Super D-string and Type IIB Superstring
Yuji Igarashi, Katsumi Itoh, Kiyoshi Kamimura +1
We show that the super D-string action is canonically equivalent to the type IIB superstring action with a world-sheet gauge field. Canonical transformation to the type IIB theory…
