Klaus Beyer (mathematician)

Klaus Hugo Beyer (born April 26, 1939 in Leipzig ) is a German mathematician who deals with sub-areas of analysis .

Live and act

Klaus Beyer attended elementary school from 1945 to 1953 and then secondary school in Leipzig and graduated from high school in 1957 . He then worked for a year as a transport worker at VEB Buchbindereimaschinenwerk Leipzig .

From 1958 to 1963 he studied mathematics at the Karl Marx University in Leipzig and graduated in 1963 as a graduate mathematician . Then he was a research assistant at the University of Leipzig and in 1966 when Herbert Beckert and Paul Guenther Dr. rer. nat. PhD . In 1968 he became senior assistant, in 1969 he obtained the Facultas Docendi and in 1970 he was appointed lecturer . In 1971 he obtained his doctorate B to become Dr. sc. nat. From 1976 to 1987 he was professor for numerical mathematics at the University of Rostock . In 1987 he was appointed full professor of analysis at the University of Leipzig. There he was head of the analysis department until 1991 and director of the mathematics section from 1990 to 1992. In 1991 his doctorate B was awarded the academic degree Dr. rer. nat. habil. and in 1992 his professorship was converted into a C4 professor for applied mathematics . In 2004 he retired .

Klaus Beyer was elected a member of the Saxon Academy of Sciences in Leipzig in 1988. From 1994 to 2000 he was the secretary of the math and science class.

Among other things, Klaus Beyer deals with partial differential equations , especially with boundary value and initial value problems , with problems of fluid mechanics and with nonlinear Fourier analysis .
