Vortices as Instantons in Noncommutative Discrete Space: Use of $Z_2$ Coordinates

Hideharu Otsu, Toshiro Sato, Hitoshi Ikemori +1

We show that vortices of Yang-Mills-Higgs model in $R^2$ space can be regarded as instantons of Yang-Mills model in $R^2\times Z_2$ space. For this, we construct the noncommu…
