Arf's influence on science in general and mathematics in particular was profound. Although he had very few formal students, many of the mathematicians of Turkey, at some time of their careers, had fruitful discussions on their field of interest with him and had received support and encouragement.

He facilitated the now-celebrated visit of [[Robert Langlands]] to [[Turkey]] (now famous for the [[Langlands program]], among many other things); during which Langlands worked out some arduous calculations on the epsilon factors of [[Artin L-function]]s.

Arf's portrait is depicted on the [[Obverse and reverse|reverse]] of the Turkish 10 [[Turkish lira|lira]] banknote issued in 2009.<ref>[http://www.tcmb.gov.tr/yeni/eng/ Central Bank of the Republic of Turkey] {{Webarchive|url=https://web.archive.org/web/20090615060512/http://www.tcmb.gov.tr/yeni/eng/ |date=2009-06-15 }}.
