Talk:Inverse of Injection is Many-to-One Relation

Am I nitpicking, or does a functon admit an inverse iff it is an injection and a surjection? It needs to be both, I thought. --GFauxPas 08:45, 18 November 2011 (CST)
 * Entirely correct. However, note that every function is a surjection onto its image. The relation defined here takes indeed the image as the domain, so no problem arises. --Lord_Farin 09:00, 18 November 2011 (CST)
 * A Functional Relation is not a Function. --prime mover 13:47, 18 November 2011 (CST)
 * Ah my b. Feel free to delete this talk page, sorry! --GFauxPas 13:48, 18 November 2011 (CST)
 * No, we'll leave it up in case someone else has the same confusion. --prime mover 13:55, 18 November 2011 (CST)

In order to remove all confusion, references to "functional relation" are being removed and replaced with references to "many-to-one relation". --prime mover (talk) 02:15, 25 July 2019 (EDT)
