Approximate vortex solution of Faddeev model
Chang-Guang Shi, Minoru Hirayama
Through an Ansatz specifying the azimuthal-angle dependence of the solution, the static field equation for vortex of the Faddeev model is converted to an algebraic ordinary differe…

Reduction of static field equation of Faddeev model
Minoru Hirayama, Chang-Guang Shi
A method to solve the static field equation of the Faddeev model is presented. For an special combination of the concerned field, we adopt a form which is compatible with the field…
