Quadratic functionals and sesquilinear forms

The problem of the representability of quadratic functionals by sesquilinear forms arises from the well-known Jordan – von Neumann characterization of inner product spaces among normed spaces via the parallelogram identity. The aim of this talk is to present some recent algebraic Jordan - von Neumann type theorems in the setting of modules over involutive rings and algebras.
