I’ll discuss a spin-off from joint work with Stanford physicists: Lenny Susskind and Adam Brown. We find an upper bound on the volume of balls in a Riemannian manifold $X$ somewhat stronger (i.e. smaller) than that obtained by comparing to the hyperbolic space of equal dimension and Ricci quadratic from agreeing with the minimum value achieved on $X$. The new idea is a method, “coefficient shuffling”, for studying correlated families of Jacobi equations.http://events.berkeley.edu/index.php/calendar/sn/math.html?event_ID=126030&date=2019-06-12
