Mini-Workshop on Matrix Analysis and Applications
This meeting aims to foster research and collaboration among mathematicians working
in various aspects of linear and multilinear algebra, matrix analysis, quantum information,
and quantum computing. The inaugural meeting, held at the University of North Florida,
led to several research publications by its participants. We aspire to establish this
gathering as a regular tradition for researchers with shared interests in matrix analysis
and quantum information.

9:30am-10:30am: Jose Franco, On some questions relating to the near order. Abstract:
In this talk, we will discuss some new questions regarding the near order. Some of
these relate to the Furuta inequality and characterizations of the chaotic order.
10:30am-11:30am: Huajun Huang, Recent progress in the orders of the Bures-Wasserstein mean and the Alpha Procrustes mean. Abstract: In this talk, we will present the progress on the exploration of the order relations in the Bures-Wasserstein mean and the Alpha Procrustes mean. A few updated results and discussions will be posted.
11:30am-1pm: Lunch time. We will have lunch at the university dinning hall.
1:30pm-2:30pm: Sejong Kim, New candidates of matrix geometric means. Abstract: There are two important geometric means of positive definite matrices, which are metric and spectral geometric means. In this talk we introduce new candidates substituting those geometric means. We study their properties by comparing with original geometric means in the view point of geodesic, operator inequality and log-majorization. Finally, we discuss with open questions and extension to multi-variable means.
2:30pm-3:30pm: Hoa Dinh, Revisit some relations between the spectral geometric mean and Wasserstein mean. Abstract: In this talk, we introduce a new form of spectral geometric mean, the Wasserstein mean, and explore its applications in studying these objects and related questions.
3:30pm-4:30pm: Sergey Belyi, Canonical L-systems and c-Entropy. Abstract: We introduce and evaluate c-Entropy and dissipation coefficient of canonical L-systems based on the multiplication operator. We also consider the coupling of such L-systems and derive explicit formulas for its c-Entropy and dissipation coefficient.
