Helene Shapiro '75 graduated Kenyon with a B.A. in mathematics, and she is from one of the first coed classes to graduate. She just retired from Swarthmore Department of Mathematics.
Abstract: In almost any problem represented with a square matrix, the eigenvalues and eigenvectors play a key role. The Gershgorin circle theorem tells us the eigenvalues of a complex matrix are contained in a certain set of circular disks that are easily computed from the entries of the matrix. The Perron-Frobenius theorem gives information about the eigenvalues of a nonnegative matrix. Both of these results are useful for Markov chains and linear dynamical systems.
This event is part of Kenyon's year-long celebration of women for the 50th anniversary of coeducation at Kenyon and the Department of Mathematics and Statistics Math Monday Series.
