Oleh Lopushansky – Doctor of Physics and Mathematics, Professor, Dean of the Faculty of Mathematics and Natural Sciences at the University of Rzeszow, Honorary Professor of Vasyl Stefanyk Precarpathian National University (since 2016).

Oleh Lopushansky was born on March 13, 1949 in Lviv region, Ukraine. In 1971 he graduated from the Faculty of Mechanics and Mathematics of Ivan Franko Lviv State University. In 1973–1975 he worked at the Computation Centre of the Institute for Applied Problems of Mechanics and Mathematics of the Ukrainian Academy of Sciences. In 1985 he started working at the Department of Functional Analysis of this Institute as a senior research worker, and since 1990 – as the Head of the Department. In 1986 he defended his thesis for the Candidate of Sciences (PhD) at the Belarusian University, and then the thesis for the Doctor of Sciences (dr hab.) at Lviv University (1994).

In 1996 Oleh Lopushansky attained the academic rank of Professor. He worked as a professor of the Department of Mathematical and Functional Analysis at Vasyl Stefanyk Precarpathian National University (2008–2012).

At Vasyl Stefanyk Precarpathian National University Oleh Lopushansky was supervising the work on several academic research project topics. With his assistance and participation, the specialized academic council for the defense of dissertations in mathematical analysis was established and has been working up to now. Since 2009, O. Lopushansky has been associate editor of the scientific journal “Carpathian Mathematical Publications”, published by Precarpathian National University. Under the supervision of Prof. O. Lopushansky, nine PhD dissertations were defended, six of them in Ukraine and three in Poland. He was an advisor for two DSc dissertations. Four of his postgraduate students now work at Vasyl Stefanyk Precarpathian National University.

Since 2012 Oleh Lopushansky is the Dean of the Faculty of Mathematics and Natural Sciences at the University of Rzeszow. With his support, students of the Precarpathian National University majoring in Mathematics, Statistics, Physics, Applied Physics, Philosophy, Archaeology have the opportunity of studying at the University of Rzeszow under the double diploma programmes.

Scientific research interests of Oleh Lopushansky lie in the area of Nonlinear Functional Analysis, Operator Theory, Generalized Functions Theory. Oleh Lopushansky made progress in developing Hardy Space Theory for functions of infinitely many variables with the use of an invariant probability measure, satisfying Kolmogorov’s consistency conditions on infinite dimensional unitary groups, and its connection with the symmetric Fock space. This allows us to use methods of Infinity-Dimensional Holomorphy for functional representations of infinite dimensional Heisenberg groups. Prof. O. Lopushansky constructed a new approach to the investigation of the operator calculus on symmetric distributions using the tensor product technic. Together with his students, he developed a polynomial analogue of the Grothendieck duality theory and associated with it the Laplace-Fourier analysis for Schwartz-Roumieu distributions, showed applications of this analysis to the construction of operator calculus of finitely many unbounded operators in convolution algebras of distributions. Also, he has important results in the theory of spectral approximations of unbounded operators in Banach spaces, where for the case of abstract operators using the interpolation theory he described Besov-type spaces and Bernstein-Jackson inequalities.
