Eléna Wexler-Kreindler facts for kids

Eléna Wexler-Kreindler was a smart mathematician from Romania. She was born on October 15, 1931, and passed away in August 1992. She spent most of her working life in France. There, she became an expert in a field called modern algebra. She studied interesting topics like Ore extensions and how mathematical structures called rings can be "filtered" or "microlocalized." These are advanced ideas in algebra.

Early Life and Education

Eléna Kreindler was born in Brăila, Romania, on October 15, 1931. In 1951, she received a special scholarship. This allowed her to study mathematics in the USSR. She spent four years at the Ural State University. This university is in a city now known as Yekaterinburg.

In 1955, Eléna finished her master's degree. Her master's paper was about "Multiplicative Lattices with Additive Basis." Her professor, Petr Grigor'evich Kontorovich, guided her work.

Career in Romania

After her studies in the USSR, Eléna returned to Romania. She joined the Mathematics department at the Polytechnic Institute of Bucharest. She started as an assistant professor.

While teaching, she also continued her research. She focused on a field called functional analysis. Her mentor for this research was Grigore Moisil. Eléna earned her Ph.D. (a very high degree) in mathematics. Her Ph.D. paper was titled "Theory of Pseudolinear Operators." In 1969, she was promoted to associate professor.

Eléna married a fellow mathematician named Dinu Wexler. She then changed her name to Eléna Wexler-Kreindler. In 1972, she and her husband moved from Romania to France.

Career in France

Starting a new career in Paris was a challenge. Eléna first worked as an associate professor at the Pierre and Marie Curie University. She later became a permanent associate professor there. In 1989, she was promoted again.

In France, Eléna focused on modern algebra. She studied complex problems in this area. Her research included Ore extensions. She also explored the "filtration" of rings. Another topic was algebraic "microlocalisation."

Eléna also helped write books. She worked with Marie José Bertin on a collection of algebra problems. She also helped with a book by Marie Paule Maliaving. This book was about "commutative algebra" and its uses in geometry and number theory.
