Lajos Takács

Lajos Takacs ( born August 21, 1924 in Maglód ) is a Hungarian- American mathematician who deals with probability theory and in particular queuing theory and stochastic processes.

Takacs studied from 1943 at the Budapest University of Technology with a Ph.D. in 1948 ( with a study of Brownian motion ) and the Habilitation ( Ph.D. in Russian system ) in 1957 with Charles Jordan ( Stochastic Processes in the theory of particle counters) .. 1945-1948 was he Wizard of Zoltán Bay, participated in the experiment on the radar echo from the moon and was from 1948 to 1955 in the Bay led by research laboratories of Tungsram. He was also from 1950 to 1958 at the Institute of Mathematics of the Hungarian Academy of Sciences and from 1953 to 1958 assistant professor at the Eötvös Loránd University. In 1958 he went abroad. He was a lecturer at Imperial College London and at the London School of Economics, 1959-1966 Professor at Columbia University, and from 1966 at Case Western Reserve University. In 1987 he became Professor Emeritus.

He was a visiting scientist at Bell Laboratories, IBM Research and 1966 at Stanford University.

He made ​​major contributions to queuing theory and introduced in 1954 independently by Paul Lévy and Walter Smith Semi- Markov processes.

In 1994 he was awarded the John von Neumann Theory Prize. He was a foreign member of the Hungarian Academy of Sciences in 1993.
