Flatness

[Bonnie Surfus (ENG)]

I have mentioned this before and got little response.  Actually, there is 
soemthing called an "eigenfunction" that has do with the non-differential 
equations, attractors, and chaotica sytsems.  I am not yet sure what an 
eigenfunction is--only saw it referenced in a book on strange attractors 
and chaotic evolutions (by David Ruelle.)
