Talk:Delta function

Untitled

I came here through the link from impulse response, so that link must be changed to point to Dirac's delta function. Obviously, Kronecker's delta has nothing to do with the unit impulse function.

Recent page move

I have undone the recent page move which incorrectly moved the page history away from this location. I have also restored the page to the last version which made sense while it was at this title.[1] By this action I am not trying to enforce the page as a redirect rather than a dab, it is just that is the last good version. I do, however, tend to agree with user:David Eppstein that the Dirac delta function is the primary topic.

The problem arose after David's edit when another editor incorrectly created a fork at Delta function (disambiguation). Everything since then has been the fallout from trying to correct that problem. There is a fuller discussion at User talk:Spinningspark/Archive 14#Delta function (disambiguation). What I have undone is everything that has arisen from that mistake, but is not in any way restricting further editing of this page. Spinning Spark 17:35, 16 April 2013 (UTC)[reply]

Per the discussion at Wikipedia talk:WikiProject Mathematics/Archive/2013/Apr#‎Delta function, a quick Google search yields 320,000 results for Dirac AND "Delta function", compared to 78,800 results for Kronecker AND "Delta function"; Google Books results yield 109,000 results for Dirac AND "Delta function", compared to 20,100 results for Kronecker AND "Delta function". In terms of Wikipedia primacy, last month Dirac delta function got 26741 hits, compared to Kronecker delta getting 6870 hits, and (just for the heck of it) Modular discriminant getting 115 hits. This is far and away enough for Dirac delta function to meet the WP:PRIMARY criteria of being a more substantial use than all other meanings combined.
