Columbia Mathematics Department Colloquium


The 13th Proof that n!/(k!(n-k)!) ≤ n!/((k+1)!(n-k-1)!) (if k< n/2)


 Doron Zeilberger  

Rutgers University



After quickly reviewing the twelve already-known proofs,

I will present yet-another-proof that, in my humble opinion, is the nicest.


[Warning: this is not going to be a proper mathematics talk, since there

is a fairly good chance that you will understand everything!

If you are offended by a math talk that you can actually understand,

you are strongly warned not to come ]
