This talk will outline work with Jakob Hansen on using sheaves of vector spaces to model the spread of opinions over social networks. By using the (Hodge) Laplacian, one can diffuse to (literally) harmonic opinion distributions where everyone expresses agreement. By programming the sheaves appropriately, private opinions can be held from frank expression.

Maps and Directions

We are about a 15 minute walk from the main 30th Street Station and 5 minutes from the University City Rail Station at 32nd and Spruce (=South Street & Convention Avenue). Coming from the airport by train (about 15 minutes): the University City Rail Station is the second stop after you leave the airport.

If you drive, the most convenient public parking is in the pay lot whose entrance is on 34th Street between Market and Chestnut Streets.
