Gevorkyan Yurii Levonovych

Professor. In 1968, he graduated from Kharkiv State University with a degree in mathematics, and holds a qualification as a mathematician and teacher of mathematics. On the job, he successfully defended his PhD thesis on the geometry of Banach spaces, which was highly praised by experts. His thesis was the first to state the correct hypothesis for solving Banach’s problem, which was later confirmed. D. in Physics and Mathematics since 1975. He was awarded the academic title of Associate Professor of the Department of Higher Mathematics in 1979. He has 45 years of teaching experience at the National Technical University “Kharkiv Polytechnic Institute” (NTU “KhPI”). He worked at Kharkiv Polytechnic Institute (KPI) as an assistant in 1968-1975, a senior lecturer in 1975-1977, an associate professor of the Department of Higher Mathematics in 1977-1987; from 1987 to 2021 he was the head of the Department of Higher Mathematics of NTU “KPI”. In 2005, he was awarded the title of Professor of the Department of Higher Mathematics.

Conducts organisational work to develop the scientific potential of the department. As the Head of the Department, he leads the work on improving the educational process and its methodological support in order to improve the methodology of teaching lecture courses, conducting practical classes; introducing modern teaching technologies (module-rating control of students’ knowledge, complex individual tasks); using a PC in a traditional course of higher mathematics, etc. He provides assistance to postgraduate students and young teachers of the department in mastering the methods of conducting classes. He was constantly involved in the work of the educational and methodological commission of the Ministry of Higher Education of Ukraine, where he participated in the development of the course “Higher Mathematics” for engineering and technical specialities of Ukrainian universities, reviewed textbooks, teaching aids. Since 1980 he has worked as a deputy chairman, and since 1988 – as a chairman of the subject commission for entrance examinations at NTU “KPI”. He heads a permanent methodological seminar of the department.

He pays considerable attention to the development of modern educational and methodological literature to improve the quality of students’ independent work. He has prepared and published more than 30 educational and methodological works, including 16 textbooks, 10 teaching aids and 3 co-authored textbooks. He has 10 textbooks and a textbook with the stamp of the Ministry of Education of Ukraine, which are basic for study and reflect modern views in pedagogy on the issues of fundamental training of engineers in mathematics. Among them is a textbook on higher mathematics, which ensures the study of the discipline “Higher Mathematics” by part-time students of the 1st and 2nd years, and under his editorship a collection of exercises with solutions for university entrants for the preparatory department was prepared and published.

Many years of experience in teaching higher mathematics at an engineering university made it possible to prepare for publication a textbook with the stamp of the Ministry of Education of Ukraine “Higher Mathematics in Examples and Problems” in two volumes, which is focused on independent work of students.

The active organisational and methodological work of Professor Gevorgyan as Head of the Department contributed to the defence of dissertations by the teachers of the Department.

During his tenure, 4 doctoral dissertations were defended (Olshanskyi V.P., Batyhin Y.V., Pirotti E.L., Hryhoriev A.L.) and 11 PhD dissertations (Polianska T.S., Chykyna N.A., Spivak N.V, Chikina N.A., Spivak A.V., Balaka M.E., Cheremskaya N.V., Marchenko T.N., Pershyna Y.V., Potanina T.V., Kulik S.I., Dukhopelnikov S.V., Antonova I.V.).

For many years, he has been actively conducting research on mathematical modelling of physical processes using the equations of mathematical physics. He was a responsible executor in 12 contractual works at the department. Among them: “Investigation of thermal deformations in powerful steam turbine units” (Central Boiler and Turbine Institute, St. Petersburg), “Investigation of electromagnetic wave propagation through inhomogeneous bodies” (KhPI, Kharkiv) and others. In the course of one of these topics, the conditions for the use of mathematical models and methods for solving Fredholm integral equations of the 1st kind, which take into account the incorrectness of the problem, based on the study of regularisation methods by A. N. Tikhonov, were derived. As a result of other studies, an analytical expression for determining the pressure field in the case of a two-dimensional distribution of the effective viscosity of a lubricating fluid was obtained.

Research interests: functional analysis, geometry of Banach spaces.
