Encyclopedia
Christoph Zenger is a German
mathematician
.
, Zenger studied physics at the Ludwig Maximilian University of Munich and did a doctorate in mathematics (theory of normed vector spaces) in 1967. In 1973 he did his habilitation in mathematics and in 1977 he became professor of mathematics at Technical University of Munich
. In 1980 he accepted an offer of a full professorship from the Bundeswehr University of Munich. In 1982 he returned to TU Munich to fill a chair in computer science. In 2000 Zenger was selected as a member of the Bavarian Academy of Sciences and Humanities
. He retired in 2005, but is still active in research.
The most important of Zenger's scientific achievements is the discovery of how to harness approximation on sparse grid
s for the efficient solution of elliptic partial differential equations
in higher dimensions.
Beside his substantial scientific work, Zenger will be remembered for his contributions to contemporary wisdom, the most notable of which have been collected in the volume Löwenzähnchen am Bachesrand.

Sparse grid
Sparse grids are numerical techniques to represent, integrate or interpolate high dimensional functions. They were originally found by the Russian mathematician Smolyak and are based on a sparse tensor product construction...

Elliptic operator
In the theory of partial differential equations, elliptic operators are differential operators that generalize the Laplace operator. They are defined by the condition that the coefficients of the highest-order derivatives be positive, which implies the key property that the principal symbol is...
