Abbas Bahri (1 Janairu 1955 – 10 Janairu 2016) masanin lissafin Tunisiya ne. Shi ne ya lashe kyautar Fermat da Langevin Prize a fannin lissafi. Ya kasance farfesa a fannin lissafi a Jami'ar Rutgers.

Ya fi yin nazarin lissafin bambance-bambance, daidaitattun daidaituwa, da bambancin lissafi (calculus of variations, partial differential equations, and differential geometry). Ya gabatar da hanyar mahimman bayanai a cikin iyaka, wanda shine mataki na asali a cikin lissafin bambancin (calculus of variations).

Tarihin Rayuwa

Bahri ya yi karatunsa na sakandare a kasar Tunisia, sannan ya yi karatu a Faransa. Ya halarci École Normale Superieure a Paris a cikin shekarar 1974, ɗan Tunisiya na farko da ya yi haka.

A cikin shekarar 1981, ya kammala karatun digiri na uku daga Jami'ar Pierre-and-Marie-Curie. Mashawarcin karatunsa shine masanin lissafin Faransa Haïm Brezis. Bayan haka, ya kasance masanin kimiyya mai ziyara a Jami'ar Chicago.

A cikin watan Oktoba 1981, Bahri ya zama malami a fannin lissafi a Jami'ar Tunis. Ya koyar a matsayin malami a École Polytechnique daga shekarun 1984 zuwa 1993. A shekara ta 1988, ya zama farfesa a jami'ar Rutgers. A Rutgers, ya kasance darektan Cibiyar Nazarin Ƙira daga shekarun 1988 zuwa 2002.
