Department of Applied Mathematics

The origins of the Department of Applied Mathematics go back to 1940, when a joint Department of Mechanics and Mathematics was established at the Faculty of Technology of Vytautas Magnus University, which later split into the Departments of Mechanics and Mathematics. In 1950 the Department of Mathematics became the Department of Higher Mathematics, and in 1962 again divided into two – Departments of General Mathematics and Applied Mathematics. The team of the department has published more than 150 different teaching and methodical tools throughout its existence, and today high international level research is developed, and highly qualified specialists are trained here.

The lecturers of the Department of Applied Mathematics train specialists in applied mathematics and take care of the mathematical preparation of all university students. More than 70 study modules have been prepared, which are studied by students of the first, second and third cycle programs of the whole university.

Modern mathematics software is used in the courses: Matlab, SAS, R, Python and e-teaching technologies and software.

Department of Applied Mathematics specializes in:

  • Mathematical methods in the study of signals complexity.
  • Application of matrix time series analysis in investigation of dynamical systems and cardiology.
  • Fragmentation and research of numerical sequences.
  • Blockchains and cryptography.
  • Investigation of symmetric and asymmetric cryptographic systems.
  • Development and investigation of the efficient digital image encoding, analysis and synthesis techniques.
  • Analytical investigation of delay systems.
  • Solution of the eigenvalue problem for some matrices with special structure.
  • Multivariate data analysis using projection pursuit.
  • Research and applications of artificial intelligence methods.

Research groups operating in the Department of Applied Mathematics:

Artificial intelligence, data analytics and modeling, head prof. Dr. Robert Alzbutas
