DESCRIPTION:Robert Ghrist\, University of Pennsylvania\n\nAbstract: There i
s a long history of networked dynamical systems that models the spread of o
pinions over social networks\, with the graph Laplacian playing a lead role
. One of the difficulties in modeling opinion dynamics is the presence of
polarization: not everyone comes to consensus. This talk will describe join
t work with Jakob Hansen introducing a new model for opinion dynamics using
sheaves of vector spaces over social networks. The graph Laplacian is enri
ched to a Hodge Laplacian\, and the resulting dynamics on discourse sheaves
can lead to some very interesting and perhaps more realistic outcomes. Add
itional work with Hans Riess extending the theory will be hinted at. The ta
lk requires no background in sheaf theory and is suitable for graduate stud
ents in the mathematical sciences.
