This could start a lot of e-mail. So, if you need to send e-mail, please
send it to me (noe at sspectra.com) and I will post a summary of the results,
Today, I had someone say that 0^0 is undefined. Somewhat surprised, I
would like to know how common this view is among sequence fans. Note that
in OEIS, we have f(0) = 1 for the function f(n) = n^n, see
This note only covers integers; for real numbers, the argument is tougher.
If you believe that 0^0 is some other number or undefined, please read the
nice piece on Math Forum:
If you still think 0^0 is not 1, please send e-mail to me so that I can
understand the problem.
