Vladimir Jurko Glaser (born April 21, 1924 in Gorizia ; † January 22, 1984 ) was a Yugoslav theoretical physicist .

life and work

He studied in Zagreb and received his doctorate there in 1953 with a dissertation that he had done in the group of Werner Heisenberg in Göttingen. There he was part of the group around Harry Lehmann , Kurt Symanzik and Wolfhart Zimmermann who developed the LSZ formalism . From 1955, Glaser headed the theoretical physics department at the Rudjer Boskovic Institute in Zagreb . From 1957 he was in the theory department at CERN . He was the leading mathematical physicist there.

He published an early monograph on quantum electrodynamics (in Croatian) in 1955, one of the first books on modern quantum electrodynamics at all. He dealt with mathematical quantum field theory and, from the beginning of the 1960s, with the analytical continuation of S matrix elements in quantum field theory such as the derivation of dispersion relations for the treatment of high-energy nucleon scattering. He worked with French physicists such as Henri Epstein (later at IHES ) and Jacques Bros , whom he met at a lecture in Paris in 1961.

He also dealt mathematically with the Schrödinger equation and the Thirring model in quantum field theory. Most recently he dealt with spin glasses.

With Henri Epstein in 1973 he developed a new mathematical treatment of perturbation theory in quantum field theory (causal perturbation theory). They recognized that the causes for the divergences in the perturbation series of relativistic quantum field theories were caused by naive multiplication of distributions and found a way to avoid this by using special causal distributions. Originally they only dealt with the case of scalar particles, but the method was later extended to higher spin and gauge theories.
