# Constantin Corduneanu

Constantin Corduneanu (July 26, 1928 – December 26, 2018) was a Romanian-American mathematician and professor of mathematics at the University of Texas at Arlington. In 2015, he was elected a titular member of the Romanian Academy; he was a corresponding member of the Academy since 1974.

## Biography

Corduneanu was born in Potângeni, Iași County, the son of Aglaea and Costache Corduneanu. 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. 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]. 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. The thesis defense the committee was composed of Miron Nicolescu, Grigore Moisil, and Nicolae Teodorescu [ro].
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). 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.
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. 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, where he taught until his retirement in 1996. He died at Medical City Arlington in 2018, at age 90.
A Festschrift in his honor, titled Mathematical Analysis With Applications, was published in 2018.
