Scientific Programme:
Research in the field of computational mathematics and computational physics, directed to the creation of mathematical methods, algorithms, and software for the numerical or symbolic-numerical solution of topics arising in experimental and theoretical studies, by using the newest computational tools. This subject area includes a wide spectrum of investigations underway at JINR in high energy physics, nuclear physics, condensed matter physics, biophysics, information technologies, etc. which demand the development of new mathematical methods and approaches for modeling physical processes, processing and analysis of experimental data. A distinctive feature of these investigations is the close cooperation of LIT with research groups from all the JINR laboratories and from Member State institutions.
