This is the second of two talks.

It is known that the circle is the shortest curve in the flat plane enclosing a given area? But what about a non-flat plane? I will discuss some results on the shape of isoperimetric regions in nonflat spaces.

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.
