SUMMARY:Distinguished Tutte Lecture - Lauren K. Williams
CLASS:PUBLIC
DESCRIPTION:[Lauren K. Williams]\n\nTITLE: Matroids\, tropical geometry\, 
 and positivity\n\nSpeaker:\n Lauren K. Williams\n\nAffiliation:\n Harvard 
 University & Radcliffe Institute\n\nZoom:\n Please email Emma Watson.\n\nA
 BSTRACT: \n\nThe theory of matroids -- a class of combinatorial objects w
 hich\nsimultaneously generalize graphs as well as vectors in a vector spac
 e\n-- was pioneered by William Tutte in his 1948 PhD thesis. Matroids\nar
 e also closely connected to the Grassmannian and the tropical\nGrassmannia
 n.  In recent years\, mathematicians and physicists have\nbeen exploring 
 positive notions of all of these objects\, finding\napplications to scatte
 ring amplitudes and shallow water waves.  In my\ntalk I will give an intr
 oduction to matroids\, tropical geometry\, and\npositivity\, and survey so
 me of the beautiful results and applications.
