# New paper on the matrix power mean

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.
