Bogomolny equation for the BPS Skyrme model from the strong necessary conditions
arXiv:1512.01231 · doi:10.1088/1751-8113/49/17/175202
Abstract
We present a systematic tool of derivation of the Bogomolny equation for the BPS Skyrme model. Furthermore, we find a generalization of the Bogomolny equation to the case corresponding with a non-zero value of the external pressure. The method is based on the concept of strong necessary conditions and can be applied to any Skyrme like theory.
Some references (with their arXiv numbers) and the arXiv numbers of the other references, have been added. Some sentence in "Introduction" and the section "Acknowledgments" have been added, too
