SUMS: Gardiner -- Circle Packing

Today’s SUMS talk is being given by Sean Gardiner. 

Abstract:
When it comes to tessellation, no simple shape is less amenable than the circle. 
The problem of fitting circles together "nicely" has been investigated under various 
interpretations, and is still the source of many unsolved questions. This talk will aim 
to briefly discuss and exemplify several circle packing problems and constructions, from 
plane-tiling to polygon-filling to Apollonian gaskets.
