Ludwig Streit

Ludwig Paul Ary Evert Streit (born June 26, 1938 in Leipzig ) is a theoretical and mathematical physicist with German and Austrian citizenship. He is considered one of the founders of White Noise Analysis.

Life

Ludwig Streit went to the Wilhelmschule (today Wilhelmsgymnasium Kassel ) in Kassel , where he took part in a test program with a focus on social studies. He graduated as the best of his year (13 times grade “very good”) on February 26, 1957, and also passed his Latinum there a year later on March 6, 1958. Here you could already see his great talent for languages. He speaks English , French and Portuguese fluently and has a basic knowledge of many other languages.

In the winter semester of 1957 he began studying mathematics and physics at the natural science faculty of the University of Göttingen . In the summer of 1960 he went to the University of Graz , where he studied theoretical physics with minor subjects in mathematics, philosophy and psychology, where he obtained his graduate degree on April 17, 1962.

After working at the II. Institute for Theoretical Physics at the University of Hamburg in the winter semester of 1961/62 , he began his doctorate at the University of Graz with Wolfhart Zimmermann and Paul Urban . On July 3, 1963 he received his doctorate “with distinction” ( on analytical properties of the exact scattering amplitude ). In the following years he worked again as a post-doctoral student at the II. Institute for Theoretical Physics at the University of Hamburg (1963–1965) and as a DFG research fellow at the seminar for theoretical physics at the ETH Zurich (1965–1967).

From 1967 he was in the physics department of Syracuse University , USA, where he was an assistant professor from 1968 to 1969. After a short stay at Bell Telephone Laboratories in Murray Hills, New Jersey 1969-1970, he went back to Syracuse University as an Associate Professor. Since 1972 he has been a professor in the physics department at Bielefeld University . From 1981 to 1985 he was director of the Center for Interdisciplinary Research (ZiF) and, from 1984, director of the BiBoS research center.

He has also been an honorary professor at the University of Graz since 1973. In Portugal, from 1989 to 1991, he held a professorship for mathematical physics at the Universidade do Minho. Since 1991 he has been a professor of mathematics and physics at the Universidade da Madeira , Funchal , Portugal. From 1995 he also headed the Centro de Ciências Matemáticas there. He has also been a visiting professor in Tunisia, Taiwan, Italy, Japan, China, Burundi, Portugal and the Philippines.

He has also been an Austrian citizen since 1963. He is in his second marriage to the mathematics professor (Universidade da Madeira) Dr. Margarida Maria Coelho Ribeiro de Faria is married and has three children.

In theoretical physics, he worked in quantum field theory , quantum mechanics as well as nuclear physics and polymer physics . In mathematics, he dealt with infinite-dimensional analysis and contributed significantly to the development of the theory of stochastic processes and stochastic analysis ( white noise ). For example, he developed and used methods of white noise analysis for the mathematical justification of the theory of path integrals (with Takeyuki Hida) in physics.
