Re: 2 pi i = 0



It's a box in which one puts something in and something comes out. That's what I was
taught by a math prof. at UCSB (ca. 1956)-- There "were" different kinds of boxes.
e.g.. single valued, identity, "well behaved", etc.

bc, who thinks he would include transforms (a fcn. in, another out)

When I studied math it was possible to have a multi-valued function.
The definition of function in use today is what we used to call a
"single-valued function."

What is the old-timers' definition of "function"?
