My main interest is in non-commutative algebra. At present that mostly means working with Iwasawa algebras and related rings.

comment Isomorphism of matrix ring over ore domain
That the maximal right ring of quotients of $Mat_n(R)$ is $Mat_n(q.f(R))$ (in your notation) follows immediately from Corollary 3.1.6 of McConnell and Robson's book `Noncommutative Noetherian rings': ams.org/bookstore-getitem/item=GSM-30

comment About the construction of the Universal Enveloping Lie Algebroid
By the way you should probably see section 1.2.5 of math.harvard.edu/~gaitsgde/grad_2009/BB%20-%20Jantzen.pdf if you haven't already.

I'm struggling to process this slightly. Do you have a reference for the first sentence?

comment An invariant number of modules over Auslander Gorenstein modules
If my interpretation above is correct then I think you are asking about the quotient category $\mathcal{M}^\mu$ in the notation of that paper.

comment An invariant number of modules over Auslander Gorenstein modules
I'm not completely sure what you are asking. Does being $\mu$-critical mean that $\mathrm{Hom}_R(M,R)\neq 0$ (ie canonical dimension $\mu$) but for every proper quotient $M/N$ of $M$, $\mathrm{Hom}_R(M/N,R)\neq 0$? In any case this paper math.washington.edu/~smith/Research/asz6.pdf of Ajitabh, Smith and Zhang is likely to be useful.
