Mathematische Zeitschrift is a well-known journal. It publishes important math research.

Khuu Tan Dat and Huynh Trung Hieu are in a photo.

Dat and Hieu did their research with help from Associate Professor Dr. Vo Hoang Hung.

They worked on the project as part of a summer program for students to learn about math research.

In the program, students learned from teachers and worked on projects they liked. Dat and Hieu liked math analysis.

The students' research is about math systems with extreme rules. It can be used in many areas like transport and image processing.

It also helps keep models stable and sets boundaries for simulations.

Dat is very happy about their achievement.

The study is about advanced math. It can be used in physics and other areas.

Dat found the research very challenging.

Dat and Hieu studied hard and worked with their teacher for many months. They discussed their project every day.

Their hard work paid off. They won a prize for their project.

The program helps students meet professors and learn about important math problems.

Dat thinks the program is a great opportunity to learn from experts.

Their teacher hopes this will help them do more math research in the future.

Before this, Dat published a paper and Hieu won prizes in a math competition.
