This contribution continues our recent studies on the algebraic Bethe Ansatz for the RTT–algebras of sp(2n) and o(2n) types. In these studies, we faced RTT–algebras which we called An. The next step in our construction of the Bethe vectors for the RTT-algebras of type sp(2n) and o(2n) is to find the Bethe vectors for the RTT–algebras An. This paper deals with the construction of the Bethe vectors of the RTT–algebra An using the Bethe vectors of the RTT–algebra An−1.

Annotation:
We extend our recent results on the Bethe vectors for the RTT-algebra of sp(4) type. We show how the Bethe vectors can be rewritten in a different form similar to the trace formula for the Bethe vectors of the RTT-algebra of the gl(3) type.

We study the highest weight representations of the RTT-algebras for the R-matrix sp(q)(4) of type by the nested algebraic Bethe ansatz. It is a generalization of our study for R-matrix of sp(4).

Annotation:
We show how to formulate the algebraic nested Bethe ansatz for RTT algebras with an R-matrix of the sp(4) type. We obtain the Bethe vectors and Bethe conditions for any highest-weight representation of these RTT algebras.

We study the highest weight representations of the RTT-algebras for the R-matrix of sp(2n) type by the nested algebraic Bethe ansatz. For special representations these models were solved by Reshetikhin and by Martins and Ramos.

We study the highest weight representations of the RTT algebras for the R matrix of o(2n) type by the nested algebraic Bethe ansatz. We show how auxiliary RTT algebra A˜ can be used to find Bethe vectors and Bethe conditions. For special representations, in which representation of RTT algebra A˜ is trivial, the problem was solved by Reshetikhin.
