Applications are now open for the quantitative linear algebra program to be held from Mar 19 - Jun 15 2018 at the Institute for Pure and Applied Mathematics (IPAM) here at UCLA. (I am one of the organisers of this program and will be in residence for the duration.)

A brutal month for leading female mathematicians. The Morawetz inequalities for nonlinear wave equations (which have since been generalised to many other nonlinear dispersive equations) are still basically the only tool we have to force long-time decay on large-data solutions to these equations; I myself have crucially relied on some version of these inequalities in several of my own papers.

I only encountered Morawetz once, when she gave the ICM Emmy Noether Lecture in Berlin in 1998. My memory of the lecture is rather hazy, but I recall she had quite a commanding presence.

This was ... more scientifically accurate than I expected.

Managed to finally see "Gifted" on the plane. A key plot point of the movie was that there was an extraordinarily talented female mathematician, and mother of a small daughter, who died at a far too early age, which made the movie especially poignant for me in view of recent events. In any event I found the film surprisingly moving (though one could tell that it was deliberately written and produced to evoke these emotions), and the actor portraying the gifted girl (McKenna Grace) was particularly remarkable.

Another plot point involved an attempt to solve the Navier-Stokes equations (!). I became intensely curious when some mathematical details to this attempt became (briefly) visible in the movie, and was rather surprised to see some calculations that I recognised, including some of my own! I had forgotten that I had actually been contacted by the movie producers about two years ago and had supplied them with some sample mathematical material from various sources. The movie also featured a surprise cameo by a mathematician friend of mine which I also enjoyed. The actual mathematics was of course mostly a MacGuffin-type plot device, but still I appreciate that the filmmakers went to some effort to make it authentic.

Apparently a mode of reasoning impervious to mathematical logic has been discovered.

Sad news. I only met Ratner briefly on one occasion. Her theorems classifying the orbits and invariant measures of unipotent flows are quite remarkable, influential, and useful (for instance, Ben Green, Tamar Ziegler, and I used a simpler variant of these results in our work on linear equations in primes and related topics). They also directly inspired a similarly remarkable analogue of these theorems for moduli spaces by Eskin-Mirzakhani and their coauthors.
Marina Ratner unexpectedly passed away on Friday.

A race between two teams of five, in which the team who has the runner that places fifth wins. What is a good team strategy for this game?
