   Brush-up.

   Then I don’t understand this paragraph:

   The use of “nevertheles” here seems illogical. The second sentence seems to instead strengthen the standpoint of the first one, in which case it would make sense to instead say “In fact” or “Moreover”.

   You could try to copy and paste the usual pre-amble, it’s not hard:

   Format: MarkdownItex> Large noncommutative algebras (say free associative algebras and alike) are typically not called quantum. Nevertheless, few authors view any noncommutative associative algebra as quantum. I do not understand where is a confusion. I see the two sentences as about quite the unlike usages of the term. Few/a few means in my understanding not many/only several. While for most people quantum is close to commutative (q-deformations, Noetherian, finite Gelfand-Kirillov dimension...), there is an exception (contrary usage) that for some (a few) quantum is any noncommutative, even _very_ noncommutative. Isn't that what has been said ? You are free to rephrase it. As far as preambles, I think they make sense once an entry/page grows beyond a single scroll; otherwise the compact version I find easier to edit and read in early development. Of course it is welcome to learn how to format it eventually, I am on the way to get used to it. Thank you.
