Description
In this talk, I want to clarify the importance of the co-property for Bethe vectors in periodic and open spin chains. Using this property, we prove several classical identities for partition functions and scalar products of vectors. We also answer some open questions in this field. I also want to present the ”attenuation” procedure, which allows us to obtain results for a periodic chain from an open one.
