How to write correctly: "inequivalent" or " nonequivalent"? I am interested in writting this word in mathematical texts.

    Both words mean exactly the same. –  Jul 01 '20 at 10:55
  • Could you give a sentence for context, please? 'Mathematical texts' is helpful but more context is better :) –  Jul 01 '20 at 11:29
  • The best thing to do might be to read other mathematical papers in the same area by established mathematicians, and use whichever term they use –  Jul 01 '20 at 11:31
  • In one book, I found the phrase: "All these subdivisions give a rather long list of inequivalent possible structures". An example from another book: "... problem of classification of all nonequivalent systems of basis vectors ...". –  Jul 01 '20 at 12:10

    Google Ngram Viewer shows that nonequivalent is twice as common as inequivalent. – Jason Bassford Jul 01 '20 at 14:13

    Thank you very much for the useful comments! I've discovered Google Ngram Viewer! – Alexey Magazev Jul 01 '20 at 17:18
