<< Let C(m,n) be the binomial coefficient which is, I believe,

C(m,n) = C(m,n-1)*(m-n+1)/n. If a is any complex number, not a
nonnegative integer, it is easy to derive the asymptotic
behaviour of the absolute value of C(a,n) as n goes to infinity.
I did not succeed in finding this formula in the literature,
except for a hint in "Analytic function theory" by Markushevich.
Could any group member kindly help me with a reference,
preferably a rather old one, since this is surely a classical
result? (The formula helps in deriving Abel's theorem on
convergence of the binomial series on the unit circle.) >>

Not what you are asking, but you might like to look at my article

The binomial coefficient function, American Mathematical Monthly, 103
(January 1996), 1-17. Also see the cover of the August-September
issue, 1995.

(The opening figures are very badly reproduced, but I can send a better
version to anyone who is interested.)
