Hans-Joachim Girlich

from Wikipedia, the free encyclopedia

Hans-Joachim Girlich (born June 10, 1938 in Breslau ; † July 23, 2018 ) was a German mathematician who mainly worked in the field of modeling stochastic processes .

Live and act

Hans-Joachim Girlich moved to Leipzig with his parents in 1940 , where he attended school and graduated from high school in 1956. From 1956 to 1961 he studied mathematics at the University of Leipzig and graduated with a diploma . He then worked as a research assistant at the University of Leipzig. In 1966, with Herbert Beckert's work on the stochastic Dirichlet problem of elliptical differential equations , he was awarded the title of Dr. rer. nat. PhD . In 1974 he obtained his habilitation and in 1975 he was appointed full professor .

From 1973 to 1977 he was Deputy Director of Education at the Mathematics Section of the University of Leipzig and from 1981 to 1991 head of the Optimization and Stochastics department . In 2003 he retired .

Girlich was a Fellow of the International Society for Inventory Research (ISIR), of which he was a member of the Executive Committee from 1986 to 1990 and chairman of the “Mathematical Modeling of Inventories” section from 1990 to 1994 . He initiated the ISIR summer schools, the first of which took place in Leipzig in 1993.

Hans-Joachim Girlich had been married since 1963 and had a son and a daughter.

Scientific work

Hans-Joachim Girlich made scientific contributions in the field of stochastic modeling, in particular in storage theory. He and his students examined both discrete and continuous models for controlling dynamic systems and multi-level decisions in the event of uncertainty and their applications. Hans-Joachim Girlich supervised around 40 doctoral students.

Hans-Joachim Girlich has published around 100 publications in scientific journals, edited volumes and encyclopedias. He has made lecture tours to the Soviet Union, the USA, Canada, Ethiopia and South Africa, among others.

Since his retirement, Girlich has mainly worked in the field of mathematical history, including in the project Algorism - Studies on the History of Mathematics and Natural Sciences .
