Jonas Kubilius

Jonas Kubilius was born on July 27, 1921 in Jurbarkas District Municipality, Lithuanian, is Mathematician. Jonas Kubilius was a Lithuanian mathematician known for his work in probability theory and number theory. An educator by profession, he worked as a lecturer and professor at various prestigious institutions including the Vilnius University and the Lithuanian Academy of Sciences. He was also the rector of the Vilnius University for 32 years. Born into a farming family in a village in Lithuania, he began displaying his brilliance at a young age. Even as a school boy he loved to study and was especially interested in science and mathematics. He understood mathematical concepts with outstanding clarity and even helped his teacher in explaining difficult mathematic equations to fellow students while in school. He seemed to be on the right track to make a brilliant career for himself when the political situation in Europe became increasingly tense. In spite of the turbulent political atmosphere he bravely continued his studies, graduated from high school, and enrolled at the Vilnius University to further his education. Eventually he embarked on a teaching career and continued his own education by working for a Doctor of Science degree from the Steklov Institute of Mathematics in Moscow. Later on he joined the Lithuanian Academy of Sciences where he promoted his scientific work in the areas of number theory and probability theory

Kubilius was born in Fermos village, Eržvilkas county, Jurbarkas district municipality, Lithuania on 27 July 1921. He graduated from Raseiniai high school in 1940 and entered Vilnius University, from which he graduated summa cum laude in 1946 after taking off a year to teach mathematics in middle school.


Kubilius had simultaneous careers at Vilnius University and at the Lithuanian Academy of Sciences. He continued working at the university after receiving his bachelor's degree in 1946, and worked as a lecturer and assistant professor after receiving his Candidate degree in 1951. In 1958 he was promoted to professor and was elected rector of the university. He retired from the rector's position in 1991 after serving almost 33 years, and remained a professor in the university.


During the Khrushchev Thaw in the middle 1950s there were attempts to make the university "Lithuanian" by encouraging the use of the Lithuanian language in place of Russian and to revive the Department of Lithuanian Literature. This work was started by the rector Juozas Bulavas, but Stalinists objected and Bulavas was dismissed. Kubilius replaced him as rector and was more successful in resisting pressure to Russify the University: he returned Lithuanian language and culture to the forefront of the University. Česlovas Masaitis attributes Kubilius's success to "his ability to manipulate within the complex bureaucratic system of the Soviet Union and mainly because of his international recognition due to his scientific achievements." Kubilius also encouraged the faculty to write research papers in Lithuanian, English, German, and French, as well as in Russian, and he himself wrote several textbooks in Lithuanian.


Kubilius organized the first mathematical olympiad in Lithuania in 1951, and he wrote books of problems for students to use in preparing for the olympiads. He was a past President of the Lithuanian Mathematical Society.


In 1952 Kubilius became an employee of the Lithuanian Academy of Sciences in the Physics, Mathematics and Astronomy Sector. He initially promoted the development of probability theory in Lithuania, and later the development of differential equations and mathematical logic. In 1956 the Physical and Technical Institute was reorganized and Kubilius became head of the new Mathematical Sector. When he became rector of Vilnius University in 1958 he gave up his duties as head and was succeeded by Vytautas Statulevičius in 1960. In 1962 he was elected a member of the Academy. He held a position as Principal Scientific Worker at the Institute of Mathematics and Informatics, which split from the Lithuanian Academy of Sciences and is now an independent state scientific institute.


In addition to his scientific and administrative work, Kubilius was a member of the Seimas (Lithuanian parliament) from 1992 to 1996.


Kubilius's scientific work was in the areas of number theory and probability theory. The Turán–Kubilius inequality and the Kubilius model in probabilistic number theory are named after him. Eugenijus Manstavičius and Fritz Schweiger wrote about Kubilius's work in 1992, "the most impressive work has been done on the statistical theory of arithmetic functions which almost created a new research area called Probabilistic Number Theory. A monograph devoted to this topic was translated into English in 1964 and became very influential." (The monograph is Probabilistic Methods in the Theory of Numbers.)
