"Positivstellensatz and semi-pre-C*-algebras"

A positivstellensatz can loosely be described as a characterisation of elements a in an algebra A that are positive under a certain class of representations. In this talk we review some classical results regarding positive polynomials and then look at a series of Positivstellensatz that can be obtained by using the framework of semi-pre-C*-algebras.
