Re: Möbius or not

Thank you! But the fulcrum stays on top of the sphere so pushing the sphere partly through the plane should give you [imath]z \mapsto kz[/imath] for small k.

Any help with the math typesetting?

Möbius or not

Am I correct in assuming that a simple reflection, e.g., [; z \mapsto \overline{z} ;] is not a Möbius transform? All Möbius transforms are analytical, conjugation is not. On a related note, in this video: http://www.youtube.com/watch?v=JX3VmDgiFnY can all the Möbius transform be achieved with the Ri...

Re: Number of holes in the Sierpinski triangle

Good clean argument about the countability. I was also doubting the disjointness, but I figured it's fine for an iterated function system and any reasonable definition should be equivalent. Now I see the encodings/enumerations.

Number of holes in the Sierpinski triangle

My first thought was that there should be uncountably many holes by some diagonal argument. Then I started wondering if the answer might be 0. Maybe they're uncountable after all, just really weird-shaped.

Could some topology guru shed some light on this?
