Mezzetti, Emilia (ed.) et al., European women in mathematics. Proceedings of the tenth general meeting, (EWM’2001), Malta, August 24–30, 2001. River Edge, NJ: World Scientific (ISBN 981-238-190-2/hbk). 149-167 (2003).
The author gives a simplified exposition focusing on the variety of complete flags. She explains how the quantum cohomology ring for the full flag variety can be used to study totally positive uni-triangular Toeplitz matrices.
