Lyudmyla Oleksandrivna Nazarova (Ukrainian: Людмила Олександрівна Назарова, published as L. A. Nazarova and also spelled Liudmila, Ludmila, or Lyudmila; born 14 May 1938 in Vologda, RSFSR[1]) is a Ukrainian mathematician specializing in linear algebra and representation theory.
With her husband, Andrei Vladimirovich Roiter, Nazarova founded the theory of representations of and differentiation of partially ordered sets,[2][3][A] and solved the second Brauer–Thrall conjecture, proving what became known as the Nazarova–Roiter theorem.
[4][5][6][B] Her research has also included pioneering work on representations of quivers,[C] and on the wild problem in matrix classification.
[1] Nazarova began her studies at Taras Shevchenko National University of Kyiv, where she met Roiter.
Together they transferred to Leningrad State University,[7] where Nazarova completed her doctorate as a student of Dmitry Faddeev.
