SUMMARY:Opinion Dynamics on Sheaves 
LOCATION:Join Zoom Meeting
DESCRIPTION:Abstract:  There is a long history of networked dynamical systems that mode
 ls the spread of opinions over social networks, with the graph Laplacian pl
 aying a lead role. One of the difficulties in modelling opinion dynamics is
  the presence of polarization: not everyone comes to consensus. This talk w
 ill describe work joint with Jakob Hansen [OSU] introducing a new model for
  opinion dynamics using sheaves of vector spaces over social networks. The 
 graph Laplacian is enriched to a Hodge Laplacian, and the resulting dynamic
 s on *discourse sheaves* can lead to some very interesting and perhaps more
  realistic outcomes.\n
