Overview

Scientific discussion meeting organised by Dr Juan Valiente Kroon and Dr Grigalius Taujanskas.

In the sixty years since Penrose’s original insight that conformal geometry could be used to study the global structure of fields and spacetimes, these ideas have become central to many parts of mathematical and theoretical physics. Today many inspired methods and frameworks exist for asymptotic analysis in general relativity. This meeting will aim to bring together researchers working on these and related topics.

The schedule of talks and speaker biographies are available below. Speaker abstracts will be available closer to the meeting date. Meeting papers will be published in a future issue of Philosophical Transactions of the Royal Society A.
