Abstract: | We study the general rational solution of the Yang-Baxter equation with the symmetry algebra sℓ(3). The R-operator which acts
in the tensor product of two arbitrary representations of the symmetry algebra can be represented as a product of simpler
“building blocks,” R-operators. The R-operators are constructed explicitly and have a simple structure. In such a way, we construct the general rational solution
of the Yang-Baxter equation with the symmetry algebra s sℓ(3). To illustrate the factorization in the simplest situation,
we treat also the sℓ(2) case. Bibliography: 23 titles.
