Volker Nollau (born March 14, 1941 in Stuttgart ; † January 3, 2017 in Dresden ) was a German mathematician , university professor and politician (CDU). He was a professor at the Technical University of Dresden as well as a brief member of the Saxon state parliament and parliamentary state secretary for science in the Biedenkopf I cabinet .


After graduating from high school in 1959, Volker Nollau studied mathematics and theoretical physics at the TU Dresden . In 1964 he received his diploma . From 1964 Nollau was a scientific assistant and from 1969 a senior scientific assistant in the mathematics section at the TU Dresden. In 1966 he was at the Faculty of Mathematics and Natural Sciences at the TU Dresden About potencies A a (0 ≤ a ≤ 1) a closed linear operator A in a Banach Dr. rer. nat. PhD . In 1971 he completed his habilitation with the work On Fractional Powers of Infinitesimal Generators, Markoff Transition Probabilities and a Class of Directed Stable Processes . From 1982 Volker Nollau was an associate lecturer. Due to his church engagement, he was not appointed professor of mathematical statistics until September 1990, despite his habilitation in 1971 .

In 1990 and 1991 he was a member of the Saxon State Parliament and Parliamentary State Secretary for Science in the Free State of Saxony.

In 1992 he was appointed professor of Stochastic Analysis and Control appointed and also director of the Institute of Mathematical Stochastics at the TU Dresden. He was a member of the Senate. From 2000 until his retirement in 2006, Volker Nollau was vice dean of the field of mathematics and since 1994 he has been chairman of the university council. Since 2006, Nollau was also honorary professor E. h. from the Vienna University of Technology and taught at the Institute for Statistics and Probability Theory. Since it was re-established in 1994, he has been a member of the Board of Trustees of the Saxon State Library - Dresden State and University Library (SLUB). In 2004/05 he was Vice President of the German Mathematicians Association (DMV).

Nollau was a Protestant, married and had three children.


Nollau has published numerous scientific publications on topics of probability theory , mathematical statistics and financial mathematics . In addition, he published more than 200 articles on the history of the humanities, churches and science.

In addition, Nollau volunteered in the Evangelical Church. Since 1978 he has been a member of the Synod of the Evangelical Lutheran Church of Saxony and since 1984 chairman of its finance committee. From 1991 to 2004 he headed the board of directors of the Moritzburg deacon house . Since 1997 he has been canon of the Wurzen cathedral chapter and since 1998 a member of the board of trustees of the Dresden University of Applied Sciences .

Volker Nollau was the initiator and one of the directors of the permanent exhibition Erlebnisland Mathematik , which opened in the Technical Collections Dresden in September 2008.

Political activity

Volker Nollau had been a member of the CDU since March 1990 and was a member of the first Saxon state parliament from October 1990. He resigned his mandate on October 23, 1991 in connection with the review of the MPs for cooperation with the Ministry of State Security . Nollau was State Secretary at the State Minister for Science and Art until he resigned on September 4, 1991 after reports in the press about previous agreements with the Stasi. During the GDR era, Nollau had been observed for years because of his work in the synod of the Evangelical Lutheran Church in Saxony and in 1988 had direct contact with the Stasi. Misconduct by Nollau could not be proven, so that the personnel commission of the TU Dresden in 1992 could not find any reason for an appointment to the mathematics chair.


On May 26, 2005, Erich Iltgen, President of the State Parliament, awarded him the Saxon Constitutional Medal for "his constant work in the Evangelical Lutheran Church of Saxony" . His commitment to the renewal of the Saxon university system after the fall of the Wall was also recognized.
