Lattice Theory & Its Applications.

Research group at the University of Szeged and in collaboration with the HUN-REN Alfréd Rényi Institute of Mathematics.

About the
research group.

The research group aims to investigate mathematical problems related to the geometric theory of lattices and to explore their applications in cryptography.

The project is funded by the Hungarian–Chinese Industrial Science and Technology Cooperation Programme under grant number 2024-1.2.8-TÉT-IPARI-CN-2025-00011.

Participating institutions: University of Szeged (SZTE), HUN-REN Alfréd Rényi Institute of Mathematics, and Jinan University.
