Factorization of the $\mathfrak{sl}(2|1)$ invariant R-matrix

This work presents a new approach to the construction of general solution of the Yang–Baxter equation with supersymmetry algebra. The factorizing R-operator acts in a tensor product of two arbitrary Verma module representations of superalgebra $\mathfrak{sl}(2|1)$. The main building blocks in construction are even and odd intertwining operators.
