Rectangular Recurrence Relations in $gl_{n}$ and $o_{2 n + 1}$ Invariant Integrable Models

Andrii Liashyk, Stanislav Pakuliak, Eric Ragoucy

A new method is introduced to derive general recurrence relations for off-shell Bethe vectors in quantum integrable models with either type $gl_{n}$ or type $\mathfrak{o}_…

Scalar products and norm of Bethe vectors in $o_{2 n + 1}$ invariant integrable models

A. Liashyk, S. Pakuliak, E. Ragoucy

We compute scalar products of off-shell Bethe vectors in models with $o_{2 n + 1}$ symmetry. The scalar products are expressed as a sum over partitions of the Bethe parameter sets, th…
