Constantin Bănică (24 August 1942 – 25 December 1991) was a Romanian mathematician known for his contributions to complex analytic geometry and to the study of vector bundles on complex spaces.[1] He was a corresponding member of the Romanian Academy and a leading figure in Romanian mathematics in the latter half of the 20th century.[2]
Biography
Bănică was born in Chișinău, Kingdom of Romania (now Moldova), in 1942. He studied mathematics at the University of Bucharest, where he obtained his Ph.D. under Corneliu Constantinescu.[3] He became a researcher at the Institute of Mathematics of the Romanian Academy (IMAR), where he spent most of his career.
His work focused on complex analytic geometry and its connections with algebraic geometry, in particular on duality theorems for Stein varieties and cohomology with compact support.[1] He co-authored several influential papers and books that introduced algebraic methods into the study of complex analytic spaces.
Bănică co-authored the book Algebraic Methods in the Global Theory of Complex Spaces (1976) with Octavian Stănășilă, a comprehensive account of algebraic geometric cohomological techniques adapted to the complex-analytic setting. The book was positively reviewed by Robin Hartshorne in the Bulletin of the American Mathematical Society.[1]

Commemoration
The Institute of Mathematics of the Romanian Academy (IMAR) named one of its main lecture halls after him — Sala 306-307 „Constantin Bănică”.[4] Numerous research seminars, including the Geometry Seminar, are regularly held there.[5]
A memorial conference, "Conferinţă în memoria lui Constantin Bănică", was held at the Institute on 25 November 2011.[6]
