DESCRIPTION:Title: <a href="https://researchseminars.org/talk/agstanford/6
 4/">Algebraic Geometry of Curvature and Matrices with Partitioned Eigenval
 ues</a>\nby Maddie Weinstein (Stanford University) as part of Stanford alg
 ebraic geometry seminar\n\n\nAbstract\nThis talk is a combined discussion 
 of an upcoming paper with Paul Breiding and Kristian Ranestad on the enume
 rative geometry of the curvature of algebraic varieties and a past paper c
 alled Real Symmetric Matrices with Partitioned Eigenvalues. Curvature is a
 n important concept in differential geometry. We approach curvature from t
 he perspective of algebraic geometry\, studying the critical curvature loc
 us of an algebraic variety. A curvature feature known as an umbilical poin
 t occurs when the eigenvalues of the second fundamental form coincide. Thi
 s leads us to a discussion of the real algebraic variety of matrices with 
 eigenvalue multiplicities determined by a partition.\n
