Just thought of starting up a blog on math. I expect to put hear real arbit stuff on math that interests me and other math enthusiasts too!
Why totient? Basically wanted the title to be some glorious mathematical symbol. Then thought of functions. The totient function certainly seemed the most exotic one. Mustn’t everything beautiful in math have something to do with Euler or Gauss? I chose Euler for the moment, but I am sure to have interesting posts on all the other geniuses like Gauss, Fermat, Galois or Ramanujan, to name a very few, and maybe even Knuth(!) or Wiles.
But the question remains — “Did Euler ever envision applications in cryptography for his seemingly innocuous function?”.
Now to the introduction of the totient function:
In number theory, the totient
