Talk:Infinite difference method

Original research?
The brief description of infinite differences doesn't include how they are implemented. The references don't contain a description of infinite differences. An online search didn't immediately turn up any research articles, apart from spurious hits where "infinite" was a typo for "finite". (This also applies to the last reference.) I suspect this article should be flagged as original research. Feydun (talk) 09:11, 31 July 2023 (UTC)
