**About the department**

The Department of Computational Mathematics and Mechanics in 2001 was organized on the basis of two existing departments of that time “Applied Mathematics” and “Mechanics and Computational Methods” and is one of the influential departments of the Faculty of Mechanics and Mathematics.

In 1961, the Department of Applied and Computational Mathematics was opened at the Tajik State University. The department was headed by V.Kh. Tashbaev. During this period, on the initiative of V.Kh. Toshboeva, a specialty in applied mathematics was opened at the department. To train specialists in this specialty, with the support of V. Tashbaev, several talented students were sent to universities in Moscow, Tashkent and Voronezh. To train specialists in this specialty with the support of V.Kh. Tashbaev several talented students were sent to universities in Moscow, Tashkent and Voronezh. In 1972, he was elected head of the department of applied mathematics at TSU named after V.I. Lenin and worked in this position until 1977. In 1977-1988, the head of this department was Associate Professor E.G. Samandarov. During this period, with the introduction of the Minsk-22 (1970) and ES1022 (1978) computers into operation, it became possible to raise the training of applied mathematics specialists to a higher level, to expand their research activities and worldview.

From 1988 to 2001, the head of the department was Associate Professor N. Shermatov. Teachers of the department gave lectures and conducted practical and laboratory classes in all departments of the Faculty of Mechanics and Mathematics on the subject of probability theory and mathematical statistics, special courses and specialized laboratories. They also gave lectures and conducted practical classes at the faculties of physics, geology and all faculties of economics on the subject of probability theory and mathematical statistics. At the department, students specialized in probability theory and mathematical statistics.

Teachers of the department carried out scientific work on the budgetary scientific topic “Probabilistic-statistical models of some applied problems”, “Research and numerical solution of some differential and integral equations” and the topic ordered by the Ministry of Education of the Republic of Tajikistan “Mathematical modeling of plant growth”.

The teachers of the department wrote and published textbooks and guidelines on all subjects of the department. Over the years, academician of the AI RT, professor Z.D. worked at the department.
