I prefer to write on the English Wikipedia rather than on the Italian one because I think knowledge should not be fragmented in many languages; rather, English should be the knowledge sharing lingua franca.
My English is far from perfect, so please correct any mistakes you find in my edits.
I am currently (as of 2021) a member of the Outreach Commitee of the International Linear Algebra Society, therefore I am in conflict of interest with some articles I plan to edit.
