Abstract

Let (X,rX)(X,r_X) and (Y,rY)(Y,r_Y) be finite nondegenerate involutive set-theoretic solutions of the Yang-Baxter equation, and let AX=A(k,X,rX)A_X = A(\textbf{k}, X, r_X) and AY=A(k,Y,rY)A_Y= A(\textbf{k}, Y, r_Y) be their quadratic Yang-Baxter algebras over a field k.\textbf{k}. We find an explicit presentation of the Segre product AXAYA_X\circ A_Y in terms of one-generators and quadratic relations. We introduce analogues of Segre maps in the class of Yang-Baxter algebras and find their images and their kernels. The results agree with their classical analogues in the commutative case.
