Biography

Corduneanu was born in Potângeni, Iași County, the son of Aglaea and Costache Corduneanu.^[3] From 1940 to 1947, he attended military high school in Iași and Predeal. In 1951, he graduated from the Faculty of Sciences of the University of Iași, Department of Mathematics.^[5] His teachers there included Alexander Myller, Octav Mayer, Mendel Haimovici [ro], Dimitrie Mangeron [ro], Ilie Popa, Gheorghe Gheorghiev [ro], Alexandru Climescu [ro], Ion L. Creangă [ro], and Adolf Haimovici [ro].^[6] Corduneanu received his Ph.D. in 1956 from the University of Iași with thesis Probleme globale pentru ecuațiile diferențiale de ordin I și II written under the supervision of Ilie Popa.^[7] The thesis defense the committee was composed of Miron Nicolescu, Grigore Moisil, and Nicolae Teodorescu [ro].^[4]

From 1949 to 1977 he was a faculty member at the University of Iași, advancing in rank to full professor, and serving as Dean of the Faculty of Mathematics (1968–1972) and pro-rector (1972–1973 and 1974–1977).^[5] He also held faculty positions at the Gheorghe Asachi Technical University of Iași and at the University of Suceava, where he served as rector from 1966 to 1968.^[5][2]

In 1977, Corduneanu decided to leave Romania. He first went to Italy, where he taught some courses at the International Centre for Theoretical Physics in Trieste.^[2] In January 1978, he emigrated to the United States, and secured a teaching position at the University of Rhode Island (where he had been a visiting professor in 1967–1968 and 1973–1974). After spending a year as visiting professor at the University of Tennessee at Knoxville, he became a tenured professor in the fall of 1979 at the University of Texas at Arlington,^[2] where he taught until his retirement in 1996.^[5] He died at Medical City Arlington in 2018, at age 90.^[3]

A Festschrift in his honor, titled Mathematical Analysis With Applications, was published in 2018.
