Gauge-Theoretical Method in Solving Zero-curvature Equations III --Gauge Theoretical Method and the Bäcklund Transformations for Solitons--
Takahiro Azuma, Takao Koikawa
In soliton theory, both the gauge-theoretical method and the Bäcklund transformation yield soliton equations from the compatibility condition of a pair of linear equations. Therefo…
Lie Algebra Quantization by the Star Product
Takao Koikawa
We apply the star product quantization to the Lie algebra. The quantization in terms of the star product is well known and the commutation relation in this case is called the -d…
An Infinite Number of Static Soliton Solutions to the 5D Einstein-Maxwell Equations with a Dilaton Field
Takahiro Azuma, Takao Koikawa
We study the 5D static Einstein-Maxwell equations with a dilaton field. We construct an infinte number of solutions by using a soliton technique. We study the rod structure of 2-so…
An Infinite Number of Static Soliton Solutions to 5D Einstein-Maxwell Equations
Takahiro Azuma, Takao Koikawa
The soliton technique is applied to the 5D static Einstein-Maxwell equations, and an infinite number of solutions are explicitly obtained. We study the rod structure of 2-soliton s…
Infinite Number of Stationary Soliton Solutions to Five-dimensional Vacuum Einstein Equation
Takahiro Azuma, Takao Koikawa
We obtain an infinite number of soliton solutions to the the five-dimensional stationary Einstein equation with axial symmetry by using the inverse scattering method. We start with…
