On the scalar products of Bethe vectors (continuation) N. A. Slavnov Steklov Mathematical Institute of Russian Academy of Sciences, Moscow |

Abstract: The concept of Bethe vector is key in the Quantum Inverse Scattering Method. Under certain conditions, these vectors become eigenvectors of quantum Hamiltonians. In the first part of my report, I discussed an ambiguity in the definition of Bethe vectors. In the second part, I will talk about a simple method for computing the scalar products of Bethe vectors. The method is based on the properties of these vectors with respect to the coproduct.
