Electrically charged quantum particles: a C*-algebraic model
Charged particles cannot be separated from the electromagnetic field surrounding them and, when scattered, they produce long-range radiation. Related to these experimental facts are difficulties in the mathematical modelling of elementary particles like electrons.
A C*-algebraic model of electrons and radiation will be discussed. It avoids the complexity of the full theory, but allows the study of the "dressing" of electrons with the electromagnetic field by an analysis of its representations.
