Jalal Eyvaz oglu Allakhverdiyev (Azerbaijani: Cəlal Eyvaz oğlu Allahverdiyev; September 17, 1929 – January 19, 2017) was an Azerbaijani mathematician and a member of the Azerbaijan National Academy of Sciences, which was called the Academy of Sciences of the Azerbaijan Soviet Socialist Republic in 1972.

He graduated from secondary school as the top student in his class, but due to lack of a Shusha certificate he could not read the price list for years.

However, the evaluation given to him by the Ministry of Education Mathematics department was subsequently changed to "good", and he was given the silver medal rather than gold.

He supervised the team of Azerbaijani schoolchildren at the International Mathematical Olympiads in India in 1996 and in Argentina in 1997.

[8] He investigated the completeness of systems of own elements of one class of not self-interfaced operators, polynomially – and rationally – depending on the parameter.
