BPS Submodels of The Generalized Skyrme Model and How to Find Them
Ardian Nata Atmaja, Bobby Eka Gunara, Ilham Prasetyo
Using the BPS Lagrangian method we show that all known BPS submodels of the generalized Skyrme model, with a particular ansatz for the fields content, can be devided into three gro…
