Education and career
Born in Reșița, Romania, Foias studied mathematics at the University of Bucharest. He completed his dissertation in 1957,[1] but was not allowed to defend his thesis by the Communist government until 1962.[2] He received his doctorate in 1962 under supervision of Miron Nicolescu.
Foias defected to France following his lecture at the International Congress of Mathematicians in 1978. He later emigrated to the United States.[1]
Foias taught at his alma mater (1966–1979), Paris-Sud 11 University (1979–1983), and Indiana University (1983 until retirement). Beginning in 2000, he was a teacher and researcher at Texas A&M University, where he was a Distinguished Professor.
The Foias constant is named after him. Foias is listed as an ISI highly cited researcher.[3]
Together with Sz-Nagy, Foias proved the celebrated commutant lifting theorem.
He died in Tempe, Arizona on March 22, 2020.[4]
