I think (fractal-analysis) and (fractals) could be merged.
The first one is barely used & almost all of it's question has the second one as a duplicated tag.

Just a few minutes back I asked this question in the MSE. However, there I got a couple of downvotes and were told to post it in PhSE. This response makes me wonder that is there any sensible reason to retain the philosophy tag?
For the responses I have got were (I will only quote two),

Suppose that the real polynomial below
$$p(x)=\sum_{k=0}^{2n}\alpha_{k}x^k$$
is a palindromic polynomial of even degree; that is, $p_{2n-k}=p_k$ for $0\leq k\leq 2n$ and $\alpha_0\neq 0$.
Is it true that the combination of Chebyshev polynomials (of the second kind) below
$$\sum_{k=0}^{2n} \...
The set-theory tag is explicitly about mathematics (and metamathematics) in the context of $\mathsf{ZFC}$ and its subsystems and extensions.
Every now and then we see questions about other set theories ($\mathsf{NF}$ is popular enough, but there are other versions, see here, for instance).

In functional analysis (a branch of mathematics), a reproducing kernel Hilbert space (RKHS) is a Hilbert space of functions in which point evaluation is a continuous linear functional. Roughly speaking, this means that if two functions
f
{\displaystyle f}
and
g
{\displaystyle g}
in the RKHS are close in norm, i.e.,
‖
f
−
g
‖
{\displaystyle \|f-g\|}
is small, then

{\displaystyle f}
and
