This is the fourth joint paper with my friends at UNF in this academic year. Our team has published 3 joint papers in Linear Algebra and Its Applications within one year working together.

# New paper in Linear Algebra and Its Applications

The third joint paper with Dr. Jose Franco and Dr. Raluca Dumitru in LAA is online now:

In this paper we investigate new characterizations of operator monotone functions by inequalities involving the matrix geometric mean.

# Fall 2017

I encourage my students working in groups. They discuss and solve problems together. Meanwhile, I go around the class to see students’ understanding, their mistakes and give hints and additional explanations, if needed. Students are excited to work with each others and help each others. This methods also gives me a way to provide some individual instruction. The solutions are collected at the end of each lecture for extra credit. My students told me that they like to study in such environment.

# The 6th International Conference on Matrix Analysis and Its Applications

The 6th International Conference on Matrix Analysis and Its Applications (ICMAA 2017) was held in Danang, a beautiful city in Central Vietnam, June 15-18, 2017. The previous conferences were held in China (Beijing, Hangzhou), United States (Nova Southeastern University), and Turkey (Selcuk University, Konya). Former keynote speakers are Roger Horn, Richard Brualdi, Chi-Kwong Li, Steve Kirkland, Alexander A. Klyachko (ILAS guest speaker), and Shmuel Friedland.

This meeting aims to stimulate research and interaction of mathematicians in all aspects of linear and multilinear algebra, matrix analysis, graph theory, and their applications and to provide an opportunity for researchers to exchange ideas and developments on these subjects.

ICMAA 2017 was supported by Duy Tan University and ILAS. We welcomed 70 participants from 17 countries to Danang. The keynote speaker of the ICMAA 2017 was Dr. Man-Duen Choi. Three invited talks were also given by famous mathematicians in matrix theory, professors Tsuyoshi Ando, Abraham Berman and Richard Brualdi.

The early registration started on June 15. All talks were on 16-17 June at the main campus of Duy Tan University. On June 18, participants visited the famous Linh Ung Pagoda and Marble Mountains in Danang city. Dr Choi opened the conference with an interesting keynote lecture on tensor products of complex matrices and his mathematical journey. He explained the connection between tensor products and quantum entanglement and the Principle of Locality in quantum information theory. We also welcomed 46 contributed talks on different topics such as: combinatorics, numerical algebra, matrix equations, graph theory, operator algebra theory, non-commutative algebraic geometry etc.

ICMAA 2017 was a very successful event. At the same time, it was an excellent introduction of many topics in matrix analysis and its applications to the Vietnamese math community. The journal Acta Mathematica Vietnamica will publish a special issue on Matrix Analysis and Its Applications in 2018. All are welcome to submit papers for this issue.
