A Radon-Nikodým type theorem for orthosymmetric bilinear operators
The author proves some new facts concerning the structure of the square of a vector lattice, characterizes orthoregular bilinear operators that may be presented as differences of symmetric lattice bimorphisms, and provide a Radon-Nikodým type theorem for orthosymmetric order continuous order interval preserving bilinear operators. At the end of the paper, the author makes many interesting remarks.
