Local and global approximation via ultraproduct
Abstract
I am going to talk on a work aimed at formalising approximation procedures in physics. The main new model-theoretic tool in this work is the notion of the ultraproduct in the classes of emerging metric structures which generalises the ultraproduct of general structures developed by J.Kiesler. In particular, the structure of Minkowski spacetime with the action of the Lorentz group is an emerging metric ultraproduct of certain finite structures invariant under the action of appropriate finite groups. Also, it is shown that any compact simple Lie group is representable as emerging metric ultraproduct of finite groups.
The University of Leeds wants to appoint at least one candidate in each of the Departments of Pure Mathematics, Applied Mathematics, and Statistics.
They particularly welcome applications from candidates with expertise in Statistical Methodology and/or the ability to teach across their portfolio of Data Science programmes.
