Valuated Delta Matroids and Principal Minors

Explore advanced mathematical concepts in this research lecture from the Geometry of Matroid Workshop where University of Washington's Cynthia Vinzant delves into valuated Delta matroids and their relationship with principal minors. Learn about the generalization of matroids through Delta matroids, examining their applications in combinatorial structures like graph matchings and principal minors of symmetric matrices. Discover the concept of valuated Delta matroids and their representability through principal minors of Hermitian matrices over valued fields, building upon Rincón's work on even Delta matroids and skew symmetric matrices. Based on collaborative research with Nathan Cheung, Tracy Chin, and Gaku Liu, gain insights into this sophisticated mathematical framework that bridges multiple areas of advanced mathematics.
