Jordan *-derivation pairs and quadratic functionals on modules over *-rings

  • B. ZalarEmail author
Research Papers


We give a new simple proof of Šemrl’s recent representation theorem for quasi-quadratic functions acting on unital modules and then show that our approach also gives a certain extension of Šemrl’s result.

This paper is intended to point out the usefulness of the ternary point of view even when we are dealing with problems which involve only binary structure.
