About JANT
JANT (Japan Algorithmic Number Theory Research Group) was established in July 2000 to promote research on number-theoretic algorithms and their applications, including practical applications in coding theory and cryptography. Our mission is to facilitate collaboration between researchers, developers, and practitioners in both industry and academia.
Activities
Since its establishment, JANT has organized and sponsored research meetings and special sessions to provide forums for academic exchange. In recent years, we have regularly hosted specialized sessions at the annual JSIAM conference.
These meetings have featured research presentations and participation from a wide range of fields centered on number-theoretic algorithms, making ongoing contributions to the advancement of algorithmic number theory and its applications.

Background
Number-theoretic algorithms and their related research fields have strong connections to coding theory and cryptology-areas that are currently receiving significant attention for their practical applications. This development has demonstrated that number theory, traditionally considered one of the most abstract areas of mathematics, can directly address critical challenges in real-world computing.
Field Development
The advancement of this field requires three key elements:
Shared access to specialized databases
Development of number theory-specific software
Active collaboration between researchers and developers from both industry and academia
Group Formation
To promote research in algorithmic number theory and its applications, the Japan Society for Industrial and Applied Mathematics has established the Research Group on Algorithmic Number Theory and Its Applications (JANT).
Initial Activities
As our primary activity, we organize regular meetings approximately every two to three months. We welcome participation from all interested researchers and practitioners in the field.
The Research Group on Algorithmic Number Theory and Its Applications (JANT) within the Japan Society for Industrial and Applied Mathematics is organized by the following members.
