Eléna Wexler-Kreindler
{{short description|Romanian mathematician}}
Eléna Wexler-Kreindler (15 October 1931 – August 1992) was a Romanian mathematician. She spent most of her professional career in France, where she specialized in modern algebra and studied the Ore extensions, the theory of the filtration of rings, or algebraic microlocalisation.{{cite journal|title = Elena Wexler-Kreindler (1931–1992) in Memoriam|journal = Journal of Pure and Applied Algebra|date = 1996|pages = 109–110|volume = 107|series = Proceedings of the Sixth International Conference "Contact Franco Belge en Algebre"|issue = 2–3|doi = 10.1016/S0022-4049(96)90081-X|doi-access = }}
Career
Kreindler was born on 15 October 1931 in Brăila, Romania into a Jewish family. She obtained in 1951 a fellowship and spent the next four years in the USSR studying mathematics at the Ural State University, located in Sverdlovsk (nowadays Yekaterinburg). In 1955, she completed a master thesis on "Multiplicative Lattices with Additive Basis" under the supervision of Petr Grigor'evich Kontorovich,{{cite journal|title = Petr Grigor'evich Kontorovich (obituary)|journal = Russian Mathematical Surveys|pages = 179–180|volume = 23|issue = 4|doi = 10.1070/rm1968v023n04abeh003771|first = A G|last = Kurosh|first2 = B I|last2 = Plotkin|first3 = H K|last3 = Sesekin|first4 = L N|last4 = Shevrin|year = 1968|bibcode = 1968RuMaS..23..179K}} before returning to Bucharest to join the faculty of Mathematics at the Polytechnic Institute of Bucharest. Next to her duties as assistant professor, she continued with her research in the field of functional analysis under the guidance of Grigore Moisil. She earned her Ph.D. thesis in mathematics on the "Theory of Pseudolinear Operators". In 1969 she was promoted to associate professor. Kreindler married fellow mathematician Dinu Wexler and changed her name to Eléna Wexler-Kreindler. She left Romania with her husband in 1972 to move to France.
She had to start a new professional career in Paris, first as untenured and later tenured associate professor at the Pierre and Marie Curie University. She was eventually promoted to associate professor in 1989. Her work in France was dedicated to the study of problems in modern algebra, such as the Ore extensions,{{cite journal|title = Polynomes de Ore, series formelles tordues et anneaux filters complets herediataires|journal = Communications in Algebra|date = 1980|issn = 0092-7872|pages = 339–371|volume = 8|issue = 4|language = fr|first = Elena|last = Wexler-Kreindler|oclc = 461444271|doi = 10.1080/00927878008822463}} the theory of the filtration of rings,{{cite journal|title = Remarques sur la localisation des anneaux filtrés|journal = Communications in Algebra|date = 1986|issn = 0092-7872|pages = 1597–1614|volume = 14|issue = 8|language = fr|first = Elena|last = Wexler-Kreindler|oclc = 4659897588|doi = 10.1080/00927878608823386}} or algebraic microlocalisation.{{cite journal|title = Microlocalisation, platitude et theorie de torsion|journal = Communications in Algebra|date = 1988|issn = 0092-7872|pages = 1813–1852|volume = 16|issue = 9|language = fr|first = Elena|last = Wexler-Kreindler|oclc = 4659903062|doi = 10.1080/00927878808823663}} She published with Marie José Bertin a collection of solved problems of algebra{{cite book|title = Algèbre commutative: applications en géométrie et théorie des nombres : exercices|publisher = Masson|date = 1986|location = Paris|isbn = 978-2225808258|language = French|first = Marie José|last = Bertin|first2 = Elena|last2 = Wexler-Kreindler|oclc = 15146879}} and a companion to the book of Marie Paule Maliaving "Algèbre commutative: applications en géométrie et théorie des nombres".{{cite book|title = Algèbre commutative: applications en géométrie et théorie des nombres|publisher = Masson|date = 1986|location = Paris|isbn = 978-2225808258|language = fr|first = Marie-Paule|last = Malliavin|first2 = Marie-José|last2 = Bertin|first3 = Elena|last3 = Wexler-Kreindler|oclc = 634779846}}
