Contributions
The Brylinski–Kostant filtration of
weight spaces is named after her. She originally developed this filtration in 1989, motivated by earlier work of
Bertram Kostant
Bertram Kostant (May 24, 1928 – February 2, 2017) was an American mathematician who worked in representation theory, differential geometry, and mathematical physics.

. She is also known for Brylinski's theorem, a theorem from her dissertation on the closures of orbits of
algebraic group
In mathematics, an algebraic group is an algebraic variety endowed with a group structure which is compatible with its structure as an algebraic variety. Thus the study of algebraic groups belongs both to algebraic geometry and group theory.

Another result, also called "Brylinski's theorem", comes from a paper written jointly by Brylinski and her husband, characterizing
universal quantum logic gates.
Recognition
