The aim of the meeting is to bring together researchers whose work relates to the interests of Paul Busch who, while holding a Leverhulme Trust Senior Research Fellowship (2017-18), passed away last year after a short illness.

Paul made many fundamental contributions to the mathematical foundations of quantum mechanics, in particular to the theory of measurement and uncertainty relations. A characteristic feature of his approach was to clarify conceptual issues besetting the foundations of quantum theory, by providing mathematically rigorous answers.
