This song was written and performed by Sachin Ramabhadran, Cassie
Riccio, and Liz Keyes, at my request. It is an homage to the topological
concept "deformation retract". To learn more about deformation retracts,
go here for a
standard mathematical definition or here
for an example involving soap bubbles.
Any questions? Ask your local topologist or e-mail me
