Dear friends and colleagues, I hope this email finds you healthy and in a good mood. In particular, in this difficult period! Besides teaching, it is also important to get our research going. Thus, we try to organize our regular PDE seminar now via Zoom. Our first talk via Zoom is David Lee (UniversitÃ© Marie-Curie, Paris) who is speaking on Monday, 20 April 2020, at 2 pm about "AN INTRODUCTION TO THE THEORY OF ROUGH INTEGRATION" An abstract to the talk can be found on http://www.maths.usyd.edu.au/u/PDESeminar/abstracts20/lee.xhtml Meeting URL: https://uni-sydney.zoom.us/j/654140370 I hope to see you all soon again (virtually, and physically to a coffee in near future) Best wishes, Daniel H.
