Geometry and Topology Seminar: Joonas Ilmavirta, University of Jyväskylä, Finland, Geophysics and algebraic geometry
April 26 | 11:30 am - 12:30 pm EDT
Many areas of interest within the Earth are anisotropic, meaning that the speed of sound is different in different directions. It turns out that pressure waves are far better behaved than shear waves, but fortunately the different polarizations are coupled together through algebraic geometry. I will explain the surprising power of algebraic geometry in the study of anisotropic inverse problems.
