SUMMARY:Tutte Colloquium - Tracy Chin
CLASS:PUBLIC
DESCRIPTION:TITLE: Valuated Delta Matroids and Principal Minors\n\nSPEAKER
 :\n Tracy Chin\n\nAFFILIATION:\n University of Washington\n\nLOCATION:\n 
 MC 5501\n\nABSTRACT: Delta matroids are a generalization of matroids that
  arise\nnaturally from combinatorial objects such as matchings\, ribbon gr
 aphs\,\nand principal minors of symmetric and skew symmetric matrices. In 
 this\ntalk\, we will define valuated delta matroids and explore their\ncon
 nection with principal minors of Hermitian matrices\, generalizing\nwork b
 y Rincón on valuated even delta matroids and skew symmetric\nmatrices. Ba
 sed on joint work with Nathan Cheung\, Gaku Liu\, and\nCynthia Vinzant.
