Fedir Mykolayovych Lyman
(22.02.1941 – 13.06.2020)
The famous Ukrainian mathematician and educator, Doctor of Physical
and Mathematical Sciences, Professor Fedir Mykolayovych Lyman passed
away on June 13, 2020 after a long illness.
Fedir Lyman was born on February 22, 1941 in the village Shcherby
(Sumy Region) in a large country family. In 1958, after graduating from
secondary school, he became a student of Makarenko Sumy State Peda-
gogical Institute. After graduating from this institute (1963), the talented
graduate was invited to work at the Department of Higher Mathematics
of this school. Since then, his entire pedagogical life has been connected
with his alma mater.
In October 1965, Fedir Lyman became a Ph.D. student of Sergei
N. Chernikov at Kyiv Pedagogical Institute (now National Pedagogical
Dragomanov University). In October 1968, he defended his Ph.D. thesis
“Groups with some systems of invariant subgroups” and became a junior

D Fedir Mykolayovych Lyman (22.02.1941 – 13.06.2020)
researcher at the Institute of Mathematics of the National Academy of
Sciences of Ukraine where he successfully worked up to August 1969.
However, his family remained in Sumy, so Fedir Mykolayovych returned
to Sumy, and on September 1, 1969 he began working at Sumy State
Pedagogical Institute as a senior lecturer. In 1972 he became an Associate
Professor of Mathematics, and in 1973 the Head of the Department of
Mathematics. His career at his institution skyrockets intensively, thus, in
1994 he became a Full Professor, and in 2005 he was named a President of
the Sumy State Pedagogical University. In September 1996, he defended
his doctoral of sciences dissertation titled “Groups with restrictions on
the normalizers of some systems of subgroups”.
F. M. Lyman’s scientific findings were related to group theory and were
associated with the study of groups in which normality and the normalizing
condition were the defining restrictions. He fully described groups in which
all non-cyclic, Abelian non-cyclic, decomposable subgroups are normal,
as well as groups with the normalizing condition for some systems of
non-cyclic subgroups. A number of his results have been devoted to the
study of the properties of various Σ-norms of a group and its influence
on the properties of a group. His publications on group theory consists of
two monographs and about 100 journal articles.
F. M. Lyman successfully combined scientific activity with organiza-
tional and pedagogical work. He was a talented teacher and mentor. His
pedagogical talent, love to mathematics, tact, sense of humor and ability
to present complex material simply, succinctly and clearly, without lost
of rigor, distinguished him as a lecturer and aroused sincere admiration
and respect from students and colleagues. Among the thousands of his
university students, mathematicians, physicists and computer scientists
graduates of Makarenko Sumy State Pedagogical University, one can count
of 5 D.Sc.’s and more than 30 Ph.D.’s. Two Ph.D. theses on group theory
were defended under his supervision.
His educational and methodical publications include manuals math-
ematics, mathematical logic, numerical systems, higher algebra. They
gained well-deserved popularity among students and instructors of many
universities in Ukraine.
F. M. Lyman’s achievements as an organizer and popularizer of sci-
ence are no less important. On his initiative, in 1982, the Department
of Mathematics of Sumy State Pedagogical Institute was host the VIII
National Symposium on Group Theory, and in 2001—the III International
Algebraic Conference in Ukraine. Fedir Mykolayovych was a member of
the editorial board of the scientific journal “Physical and Mathematical
Fedir Mykolayovych Lyman (22.02.1941 – 13.06.2020) E
Education”, a member of the editorial committees of a number of interna-
tional conferences. He actively worked with his disciples and students. For
20 years he was the chairman and a member of the jury of the student
mathematical Olympiads.
His accomplishments were recognized by the public and government,
among others he was awarded by the honorary title “Honored Educator of
Ukraine”.
We express our deepest and sincerest sympathy to the family and
friends of Fedir Mykolayovych, to the faculty and staff of Makarenko Sumy
State Pedagogical University. The bright memory of this outstanding
scientist and great person will forever remain in the hearts of all who knew
him and had the honor to work with him.
