comment Decomposition of a regular graph and connected subgraphs
That would be true if you required your graph to be transitive, but I don't see how mere regularity gets you there.

comment Decomposition of a regular graph and connected subgraphs
The comments on my answer lead me to wonder: is the condition on the successive decompositions supposed to hold for every possible choice of the $x_i$, or just for one?

comment Characterizing orthants with polynomials
It does sound familiar, but all I could find was this question on math.se: math.stackexchange.com/questions/966633/…

comment Characterization of a subset of [0,1] $II$
Given the possibility of excluding arbitrary countable subsets, I guess the restriction has to be that for $t\in T, t\neq 1$, the intersection $T\cap[t,t+\delta]$ must be uncountable for all $\delta>0$.

comment An extension of the real semiring with multiple degrees of infinity
I still don't quite get the "dominance" property of divisibility; assuming $(a/b)*b$ should be $a$, your second example gives $2^*=1^*+2^*$, so that either $1^*=0$, or your semiring is not cancellable - are you ok with the latter?
