Let $f$ be strictly increasing on $\mathbb{R}$. Then $x \oplus y := f^{-1}(f(x)+f(y))$ gives rise to a strict symmetric monoidal ($\Rightarrow$ commutative monoid) structure on $(\mathbb{R},\ge)$ with monoidal unit $f^{-1}(0)$. If $f(x) := \exp(x/h)$ for $h > 0$, then $([-\infty,\infty],\oplus,-\infty,+,0)$ is "the" widely used log semiring.
If $f(x) := \sigma(x)|x|^p$ for $p > 0$, then $(\mathbb{R},\oplus,0,\cdot,1)$ is also a semiring.
This semiring does not appear to be widely used, and it is not well-known to me. What is it called, and where can I find references to it in the literature?
NB. I imagine that both of these semirings are morally unified under the aegis of "associated homogeneity" in the sense of Gel'fand and Shilov, i.e., with $\log$ a variant of homogeneous of degree zero.
