Roswitha März , b. Klaus (born October 15, 1940 in Warnsdorf ) is a German mathematician and professor of numerical mathematics .

Life

März studied mathematics from 1960 to 1965 at the Zhdanov State University in Leningrad, now St. Petersburg State University in the Russian Federation , among others with Gleb Pavlovich Akilow , Solomon Grigoryevich Michlin and Ivan P. Mysovskich . The Leningrad School of Functional Analytical Applied Mathematics and Numerical Mathematics had a lasting influence on the working methods and interests of March. March graduated in 1965 with Valerii Y. Rivkind , a student of Olga Alexandrovna Ladyschenskaja , with a thesis on the numerical solution of singular partial differential equations .

From 1966 to 1970, März was a research assistant at the computing center of the Humboldt University in Berlin (HUB) with Gunter Schwarze and Manfred Peschel , where she worked on control theory , system analysis and operator calculation. In this time of March 1970 as a topical at the most prominent of the Numerical Mathematics University of the East, the Institute of Technology Karl-Marx-Stadt at Frieder Kuhnert with a thesis on numerical approximation by exponential functions to Dr. rer. nat. PhD .

From 1970 to 1974, März was senior assistant in the mathematical cybernetics and computing technology department of the mathematics section of the Humboldt University in Berlin, where she was awarded the Facultas Docendi for mathematical cybernetics and computing technology in 1972 . She worked on problems of optimal control and the numerical treatment of differential equations . In 1974, March was appointed to a lectureship in numerical mathematics at the Humboldt University in Berlin and thus switched to the newly established department of numerical mathematics at the HUB. From 1976 to 1986 she was its director. In 1978, März obtained the academic degree of Dr. with a thesis on parametric interpolation methods as an external course at the Technical University of Karl-Marx-Stadt. sc. nat. (PhD (B)). This made her the first woman at this academic level in numerical mathematics in Germany, which is comparable to the habilitation .

In 1980, March was also the first woman in Germany to be offered a full professorship for numerical mathematics. From 1980 she worked as a full professor for numerical mathematics at the Humboldt University in Berlin, from 1992 there as a university professor for mathematics / numerics. She also held visiting professorships and research stays in Caracas , Kaiserslautern , Hamburg , Leningrad , Warsaw , Budapest and Moscow , among others .

Inspired by an encounter with John C. Butcher , from 1981 onwards March largely devoted himself to the study of implicit ordinary differential equations, especially differential-algebraic equations . Together with employees and students of her working group as well as external colleagues, März worked out the fundamentals of the analysis and numerical treatment of differential-algebraic equations, including the theory of projector-based analysis, tractability index and regularity areas, complete decoupling of regular linear differential-algebraic equations, a characterization of differential-algebraic equations algebraic operators in natural function spaces and error analysis for numerical methods. Her co-authors include Eberhard Griepentrog, René Lamour, Caren Tischendorf, Michael Hanke, Katalin Balla, Galina A. Kurina, Ricardo Riaza, Vu Hoang Linh, Inmaculada Higueras and Ewa B. Weinmüller.

In 1988, March was elected a corresponding member of the Academy of Sciences of the GDR (AdW). She belonged to the computer science / cybernetics / automation class of the learned society of the AdW. In 1993 she was one of the founding members of the Leibniz Society for Science in Berlin .

From 1985 to 1990, März was a member of the Scientific Advisory Board "Mathematics" at the Ministry of Higher Education and Technical Education (MHF), and from 1988 she was deputy chairman of the Advisory Board. From 1993 she worked for two programs as a member of the "Mathematics" expert committee at the Federal Ministry of Education and Research (BMBF).

In 1990 and 1991, March was elected director of the mathematics section and dean of the mathematics department at the HUB. In protest against the restriction of her co-determination rights by the law supplementing the Berlin Higher Education Act of July 18, 1991, she resigned from this office in 1991.

On various committees, März has been intensively committed to promoting equal opportunities for women and men in science. From 1994 to 1997 she was, among other things, founding chairwoman of the German Association of Female University Teachers (DHB), a nationwide organization promoting equal opportunities for women and men at academic institutions. In November 1995, on her initiative, a regular workshop with a balanced number of women and men was held for the first time at the Mathematisches Forschungsinstitut Oberwolfach among participants and speakers.
