SUMMARY:Graphs and Matroids Seminar - Zach Walsh
CLASS:PUBLIC
DESCRIPTION:TITLE: Quadratically Dense Matroids\n\nSpeaker:\n Zach Walsh\n
 \nAffiliation:\n University of Waterloo\n\nRoom:\n MC 5479\n\nABSTRACT:\n\
 nWe discuss recent work proving that for any integer $t\\ge 2$\, any\nmaxi
 mum-sized simple $\\mathbb C$-representable matroid $M$ of large\nrank wit
 h no $U_{2\,t+3}$-minor satisfies $|M|=t{r(M)\\choose 2}+r(M)$.\nIt was no
 t our intention to prove this result\, so we will first\nexplain our origi
 nal motivation. We assume only basic knowledge of\nmatroid theory.
