Livsic graduated from school in 1931 and, with a school friend, planned his future studies. His aim was to study philosophy but first he would have to study physical sciences. However to be successful in the physical sciences Livsic and his friend would first have to become knowledgeable in mathematics. However, as he wrote, see :
Livsic began studies at Odessa technical College aimed at his becoming a radio technician but, in 1933, he entered the Department of Physics and Mathematics at Odessa State University. This department had only recently opened. There he was taught by M G Krein , M A Naimark and, a couple of years later, by B Ya Levin. He was particularly interested in the courses in complex variable, integral equations and differential equations . These courses presented the latest research results. Livsic took part in the functional analysis seminar and studied analytic functions. In fact :
He remained at Odessa working for his doctorate under Krein 's supervision. However his interests changed over time. His Master's Degree was achieved with a thesis in quasianalytic functions, then he became interested in operator theory which came out of earlier work he had done on the moment problem. At this time Livsic's studies were much influenced from his reading works by M H Stone , von Neumann , N I Akhiezer and A Y Plessner . During World War II Livsic avoided military service since his eyesight was poor. However he had to leave Odessa as the German armies advanced and his studies were somewhat disrupted. It was 1942 before he was able to defend his doctoral thesis on Hermitian operator theory and the generalised moment problem. His habilitation thesis on generalisations of von Neumann 's extension theory was examined in 1945 by a powerful groups of mathematicians, namely Banach , Gelfand, Naimark and Plessner at the Steklov Institute. At the end of World War II, Livsic as not invited to return to his post at Odessa since:
Krein was dismissed from his post and the school of functional analysis closed. After working at Kirovograd, Livsic returned to Odessa to teach at the Hydrometerological Institute which was a minor institution. He remained there until 1957, publishing results on applications of his functional analysis results to quantum theory . From 1957 until 1962 Livsic was head of mathematics at Kharkov Mining Institute, joining Akhiezer at Kharkov State University in 1962. In 1975 Kharkov made active moves to enable him to go to Israel. He first took a post in the Institute of Agricultural Machines in Tbilisi, then after three years he was able to go to Israel where he was appointed to Ben Gurion University in 1978. Again he began building a research school in operator theory. He is described in as follows:
