Partition

Calculus Level 4

For positive integer n n , let f ( n ) f(n) represent the number of distinct ways of representing n n as a sum of positive integers.

For example f ( 4 ) = 5 f(4)=5 because 4 4 can be written as 1 + 1 + 1 + 1 = 1 + 1 + 2 = 1 + 3 = 2 + 2 = 4 1+1+1+1=1+1+2=1+3=2+2=4 .

Find lim n ln ( f ( n ) ) n \displaystyle \lim_{n\to\infty}\dfrac{\ln\left(f(n)\right)}{\sqrt{n}}

π 3 2 \pi\sqrt{\dfrac{3}{2}} π 2 \dfrac{\pi}{\sqrt2} π 2 3 \pi\sqrt{\dfrac{2}{3}} π 3 \dfrac{\pi}{\sqrt3}

The asymptotic value of the Partition Function is well known........Read this and the references within......

I've just read this article: Ramanujan: Dream of the possible .😄
