Irvine-London-Munich-PoliMi-Salzburg Conference in Philosophy and Foundations of Physics Workshop: "Symmetry and Equivalence in Physics" Dates: September 2-4, 2019 Venue: HS 301, Franziskanergasse 1, 5020 Salzburg (Austria) Over the past decades, important contributions to the mathematical and conceptual foundations of physical theories have been made within the philosophical community. Conversely, critical analysis of the formal structures of our best physical theories inform central philosophical concerns, and in some cases new theorems have been proven and new lines of argument developed that are of philosophical significance. This conference series aims to bring together philosophers, physicists, and mathematicians working on such issues. This year’s event will be held on September 2-3, 2019 at the University of Salzburg (Austria). It will immediately precede a workshop on “Symmetry and Equivalence in Physics” taking place on September 3-4, 2019. Speakers for the workshop include Adam Caulton (Oxford), Ben Feintzeig (Washington), Doreen Fraser (Waterloo), Karen Crowther (Geneve), Giovanni Valente (Milan), and David Wallace (Pittsburgh).
