# Tags "riemann-zeta-function" and "zeta-functions" are almost identical

I have discovered that the following two tags are too similar to each other:

The Riemann zeta function is the function of one complex variable $$s$$ defined by the series $$\zeta(s) = \sum_{n \geq 1} \frac{1}{n^s}$$ when $$\operatorname{Re}(s) > 1$$. It admits a meromorphic continuation to $$\mathbb{C}$$ with only a simple pole at $$1$$. This function satisfies a functional equation relating the values at $$s$$ and $$1-s$$. This is the most simple example of an $$L$$-function and a central object of number theory.

and no tag wiki;

The Riemann zeta function is defined as the analytic continuation of the function defined for $$\sigma > 1$$ by the sum of the preceding series.

and tag wiki

The Riemann zeta function, $$\zeta(s)$$, is a function of a complex variable $$s$$ that analytically continues the sum of the infinite series

$$\zeta(s) =\sum_{n=1}^\infty\frac{1}{n^s}$$

which converges when the real part of $$s$$ is greater than $$1$$.

There are two problems here:

1. does it make sense to have one tag dedicated to just the Riemann $$\zeta$$, and a single other one for the rest of the $$\zeta$$ functions? A single tag for all these functions should suffice.

2. if we still want tags to distinguish between Riemann and "non-Riemann" $$\zeta$$ functions, then the latter class of functions should be correctly described in the tag description and tag wiki - a thing that does not currently happen with the latter tag.

My suggestion is to just melt the former tag into the latter, and automatically retag all the questions.
