This question is basically an extension of the following fact: given a finite dimensional, associative, unital $k$-algebra $A$, then the vector dual $A^*$ is a coassociative, counital coalgebra with coproduct $\Delta : A^* \rightarrow A^*\otimes A^*$ given by $\Delta(f)(a\otimes b) = f(ab)$.

New post in the "tag management 2017" thread about the situation regarding "Poisson" probability theory tags, that is: poisson-process, point-processes, and poisson-random-measures. Any feedback welcomed.
@Did When I click on poisson-random-measures. So I guess you have already removed the tag from the questions containing it, right?
Just for the record, I will list the questions where the tag has been removed. (It is possible that I missed some.) Since they were bumped because of retag, if there are some further improvements and somebody is willing to invest a bit of time in those post, this might be a good time to do so.
If you can confirm that before you start retagging there were 9 questions tagged poisson-random-measures, this should be all of them.
