DESCRIPTION:Gordon Royle (UWA)\n\nwill speak on\n\nChromatic roots of grap
hs and matroids\n\nat 3pm Friday May the 23rd in Weatherburn Lecture Theat
re.\n\n\nAbstract: \n\nThe location of the real and/or complex roots of th
e chromatic polynomial of a graph has been studied for many years\, both b
y combinatorial mathematicians and statistical physicists\, yet despite th
is many fundamental questions remain unsolved. And even though the chromat
ic polynomial is most generally a matroidal concept\, very little indeed i
s known about the location of chromatic roots of matroids that are not gra
phic or cographic. In this talk\, I will present a necessarily-personal su
rvey of the major results and my favourite open problems in this area. \n\
