Re: "manifold" in mathematics

This is why I like to ask questions of PEOPLE: because when you get
conflicting answers, you have somewhere to go to try and resolve the
conflict.  

So I have three different definitions of a manifold:

1. A patchwork made of many patches

2. The structure of a manifold is encoded by a collection of charts that
form an atlas.

3. a "function" that violates the usual function rule that there can be
only y value for each x value.  (or do I have that backwards).

I can map 1 or 2 on to one another, but not three.  i think 3. is the most
like meaning that Holt has in mind because I think he thinks of
consciousness as analogous to a mathematical formula that generates outputs
(responses) from inputs(environments).  

Thanks, everybody.
