Rectangular Recurrence Relations in ${\mathfrak{gl}}_n$ and ${\mathfrak{o}}_{2n+1}$ 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 ${\mathfrak{gl}}_n$ or type $\mathfrak{o}_…
