Euclidean wormhole solutions of Einstein-Yang-Mills theory in diverse dimensions
Katsuhiko Yoshida, Satoru Hirenzaki, Kiyoshi Shiraishi
We solve the Euclidean Einstein equations with non-Abelian gauge fields of sufficiently large symmetry in various dimensions. In higher-dimensional spaces, we find the solutions wh…
A New Vector-Tensor Theory and Higher-Dimensional Cosmology
Katsuhiko Yoshida, Kiyoshi Shiraishi
A new vector-tensor model of classical gravity, which contains coupling between the field strength of the vector field and the curvature tensors in six dimensions, is proposed. Cos…
Hyper-elliptic Nambu flow associated with integrable maps
Satoru Saito, Nokiko Saitoh, Katsuhiko Yoshida
We study hyper-elliptic Nambu flows associated with some dimensional maps and show that discrete integrable systems can be reproduced as flows of this class.
Nambu-Hamiltonian flows associated with discrete maps
Satoru Saito, Akira Shudo, Jun-ichi Yamamoto +1
For a differentiable map that has an inverse, we show that there exists a Nambu-Hamiltonian flow in which one of the initial value, say $…
A Characterization of Discrete Time Soliton Equations
Satoru Saito, Noriko Saitoh, Jun-ichi Yamamoto +1
We propose a method to characterize discrete time evolution equations, which generalize discrete time soliton equations, including the -difference Painlevé IV equations discusse…
A Hamiltonian Flows Associated with Two Dimensional Map
Satoru Saito, Akira Shudo, Jun-ichi Yamamoto +1
For a given differentiable map , which has an inverse, we show that there exists a Hamiltonian flow in which x plays the role of the time variable while y…
