Education and Academic Career
Krieger studied mathematics and physics at the Ludwig-Maximilians-Universität München from 1959. He obtained his doctorate in 1968 under Elmar Thoma with the thesis "Über Maßklassen" (About Measure Classes). During his studies, Krieger also attended Harvard University from 1962 to 1965, earning a master's degree in 1964. This period of academic growth laid the foundation for his future research endeavors.
After completing his master's degree, Krieger returned to Munich, where he served as a research assistant from 1966 to 1968. He then transitioned to Ohio State University, holding positions as assistant professor (1968), associate professor (1970), and full professor (1972). In 1973-1974, Krieger was a visiting professor at the University of Göttingen, further expanding his academic horizons.
Research and Contributions
Krieger's research focuses on ergodic theory, dynamical systems, and operator algebras. He introduced the concept of Cuntz-Krieger algebras in 1980, which are named after him and Joachim Cuntz. This work has had a lasting impact on the field of mathematics, with Cuntz-Krieger algebras remaining a crucial area of study.
Throughout his career, Krieger has held various visiting positions at prestigious institutions, including the IHES (Institut des Hautes Études Scientifiques) and Paris VI University in 1977-1978, the University of Ottawa in 1982-1983, the Almaden Research Center of IBM in 1988-1989, and the Hebrew University of Jerusalem in 2005-2006. These visits demonstrate Krieger's dedication to collaboration and exchange with other mathematicians.
Recognition and Awards
