DESCRIPTION:Title: Algebraic Geometry of Curvature and Matrices with Partitioned Eigenval
ues\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
