On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
On a regular tree, assign each vertex a random independent value. Two players alternate choosing a child of the current vertex. When reaching level n, player 1 receives from player 2 the cumulative sum of the values along the chosen path. We show that in some cases the value of this game converges as n\to\infty. Joint with Gourab Ray and Yinon Spinka.
