SUMMARY:Algebraic Graph Theory Seminar - Kate Lorenzen
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Spectral Properties of the exponential dist
 ance matrix\n\nSpeaker:\n Kate Lorenzen\n\nAffiliation:\n Linfield Univers
 ity\n\nZoom:\n Contact Soffia Arnadottir\n\nABSTRACT:\n\nGiven a graph $G$
 \, the exponential distance matrix is defined\nentry-wise by letting the $
 (u\,v)$-entry be $q^{dist(u\,v)}$ where\n$dist(u\,v)$ is the distance betw
 een the vertices $u$ and $v$ with the\nconvention that if vertices are in 
 different components\, then\n$q^{dist(u\,v)}=0$. We establish several prop
 erties of the\ncharacteristic polynomial (spectrum) for this matrix and th
 e inertia\nof some graph families.\n
