SUMMARY:Algebraic Graph Theory Seminar - Shaun Fallat
CLASS:PUBLIC
DESCRIPTION:TITLE: Various Maximum Nullities Associated with a Graph\n\nSp
 eaker:\n Shaun Fallat\n\nAffiliation:\n University of Regina\n\nZoom:\n Co
 ntact Soffia Arnadottir\n\nABSTRACT:\n\nGiven a graph\, we associate a col
 lection of (typically symmetric)\nmatrices S whose pattern of non-zero ent
 ries off of the main diagonal\nrespects the edges in the graph. To this se
 t\, we let M denote the\nmaximum possible nullity over all matrices in S. 
 Depending on the\nchoice of the set S\, and the family of graphs considere
 d\, the\nparameter M often corresponds to an interesting combinatorial\nch
 aracteristic (planarity\, connectivity\, coverings\, etc.) of the\nunderly
 ing graph.
