Scientific Conference for Graduates “Applied Mathematics and Computing”

Since 2009, annual Scientific conference for undergraduates and graduates “Applied Mathematics and Computing” has been held at the Faculty of Applied Mathematics.

The conference, among others, includes “Applied Mathematics” section. Conference proceedings are published after the conference.

Collaborative Monographs Whose Joint Authors are Department Faculty

Since 2010, department faculty, graduates, and students participated in writing a number of collaborative monographs:
