Abstract

We exhibit a recurrence relation for the Ramanujan’s tau-function involving the sum of divisors function, whose solution gives a closed formula for $\tau(n)$ in terms of complete Bell polynomials. Besides, we show that it is possible to write $\tau(n)$ in terms of the compositions of $n$.

Keywords and Phrases
