- TL;DR Summary
- sum ##\frac{1}{n^c}## where ##c\gt 1##

##\sum_n \frac{1}{n^c}## converges for ##c\gt 1##. Is there an expression for the value of the sum as a function of ##c##?

For some values there are analytic expressions. It's the Riemann zeta function.

I should have known! It is the zeta function for all ##c\gt 1##.For some values there are analytic expressions. It's the Riemann zeta function.
