Aleksandar Ivić

Aleksandar Ivić (March 6, 1949 – December 27, 2020) was a Serbian mathematician, specializing in analytic number theory. He gained an international reputation and gave lectures on the Riemann zeta function at universities around the world.

Biography

Aleksandar Ivić was born in Belgrade to two renowned linguists, the academician Pavle Ivić (1924–1999) and the academician Milka Ivić (1923–2011). His paternal grandfather was the historian Aleksa Ivić (1881–1948) and his maternal great-grandfather was the poet Vojislav Ilić (1862–1894), the son of the writer and minister of justice Jovan Ilić (1824–1901).

In 1967, Aleksandar Ivić successfully participated in the International Mathematical Olympiad. He graduated in 1971 from the University of Novi Sad with a bachelor's degree in science. As a graduate student in Faculty of Sciences of the University of Belgrade, he graduated with a master's degree in 1973 and a doctorate in 1975. His doctoral dissertation O nekim klasama aritmetičkih funkcija koje su vezane za raspodelu prostih brojeva (On certain classes of arithmetic functions linked to the distribution of prime numbers) was supervised by Đuro Kurepa. After working as an assistant from 1971 to 1976 at the Faculty of Science and Mathematics at the Faculty of Science and Mathematics at the University of Novi Sad, Ivić was appointed as assistant professor at the Faculty of Mining and Geology at the University of Belgrade in the Department of Applied Mathematics. There he was an assistant professor from 1976 to 1982, an associate professor from 1982 to 1988, and a full professor from 1988 to 2014, when he retired as professor emeritus.

Ivić was a member of the Mathematical Institute of the Serbian Academy of Sciences and Arts (SANU) and served on the editorial boards of several international journals. He was a plenary lecturer at several international scientific conferences. He was a visiting professor at several universities around the world in Japan, China, Brazil, Finland, and elsewhere. He was recognized as one of the world's leading experts on analytic number theory related to the Riemann hypothesis and the Lindelöf hypothesis.

The bibliography of articles authored or coauthored by Ivić contains 231 titles. He was elected in 1988 a corresponding member in 1988 and in 2000 a regular member of the Serbian Academy of Sciences and Arts (SANU).

His Erdős number is 1, as he published papers with him in 1980 and 1986.

Personal life

Aleksander Ivić married Milika Avramov in 1976. They divorced in 1990. From his first marriage, he became the father of two daughters, Natalija (born 1980) and Emilija (born 1984). His second marriage was to Sanda Rašković Ivić, whom he married in 1996. They became the parents of a daughter and two sons. Their younger son Jovan (1997–2022) committed suicide.

Ivić died in Belgrade.
