Consider a function $f(k)$ defined for positive integers $k=1,2,\cdots \infty$ the function is satisfies the condition $f(1)+f(2)+\cdots = p/(p-1)$, where $0, how to determine f(k) from this information?

    There are infinitely many (indeed uncountably many) functions $f$ such that $\sum_{k=1}^\infty f(k)=\frac{p}{p-1}$.2011-11-12
