From what I've read earlier, the definition of a BPS soliton is a soliton satisfying a Bogomolny bound (mass bounded from below). Now, I have encountered another definition, which says that a BPS soliton is a soliton preserving (at least some) supersymmetry. I don't really understand the connection between these two definitions. An explanation of this matter would be much appreciated!
Thanks in advance!
