DESCRIPTION:Speakers: Eva-Maria Hekkelman (MPIM)\n\nHigher Differential Ge
 ometry Seminar\nMusical intervals which sound pleasant\, consist of freque
 ncies that are rational multiples of each other. In joint work with Malte 
 Leimbach and Oliver Fürst\, we show that the sound of a generic drum (i.e
 . the spectrum of the Laplacian on a Riemannian manifold) contains no such
  harmonies at all. Our theorem has implications for a physics-inspired res
 earch programme by Alain Connes and Walter van Suijlekom in noncommutative
  geometry. In my talk\, I will explain our result and the key ideas in thi
 s research programme\, and how they are related.\n\nhttps://math-events.un
