London workshop on arithmetic geometry and homotopy theory

At Imperial College London, from May 30th to June 1st. Many interesting talks, but the main theme appears to be the recent work of Harpaz and Schlank in which they use etale homotopy theory to study rational points and in particular obstructions to the local-global principle. Their big preprint is available here.

Related to this theme there is also a longer summer course in Lausanne in July/August with lectures by Harpaz and Schlank, as part of the of the EPFL program on rational points and algebraic cycles.

AMS meeting and video lectures on SAGE and elliptic curves

Trying to move (temporarily) from the abstract world of stable motivic homotopy theory, I have signed up for the SAGE course at the upcoming AMS meeting in Boston. As preparation for this, I found some video lectures from MSRI (thanks to the numbertheory.org rss feed), giving an introduction to computing with elliptic curves in SAGE.

Among many other things, the AMS meeting also offers a healthy dose of homotopy theory, some lectures of Harpaz and/or Schlank on their remarkable paper on etale homotopy theory and rational points on varieties, and a special session with the amazing title Generalized Cohomology Theories in Engineering Practice. Maybe there will also be a MathOverflow meetup?
