Abraham van der Sluis

from Wikipedia, the free encyclopedia

Abraham (Bram) van der Sluis (born November 15, 1928 in Utrecht ; † March 20, 2004 ) was a Dutch mathematician who was considered the doyen of numerical mathematics in the Netherlands. He was a professor at the University of Utrecht .

Van der Sluis studied mathematics and physics in Utrecht from 1946 (Doctoraalexamen 1952 cum laude) and received his doctorate in 1956 under Jan Popken at the University of Amsterdam (General Orthogonal Polynomials). As a post-doctoral student he was in Canada (New Brunswick) and, on his return, assistant to Hans Freudenthal in Utrecht. He became interested in computers at an early age and built the computer center at the University of Utrecht (of which he was director until 1970), for which he also spent a few months at the ETH Zurich with Eduard Stiefel and Heinz Rutishauser . In 1962 he became professor for numerical mathematics in Utrecht. In 1988 he retired.

In numerical mathematics, among other things, he dealt with condition numbers and the CG method .

His doctoral students include Robert Mattheji and Henk van der Vorst .
