Mary Ellen Rudin

from Wikipedia, the free encyclopedia

Mary Ellen Rudin (born Mary Ellen Estill; born December 7, 1924 in Hillsboro , Texas ; † March 18, 2013 ) was an American mathematician who studied topology.

Live and act

Rudin studied at the University of Texas at Austin with Robert Lee Moore , where she received her bachelor's degree in 1944 and her doctorate in 1949 ( Concerning abstract spaces ) on variations on Moore's system of axioms of the topology of point sets. Then she was an instructor at Duke University in Durham (North Carolina) through Moore . 1953 to 1958 she was an associate professor at the University of Rochester , where her husband was Walter Rudin , whom she met at Duke University and married in 1953 (with him she had two daughters and two sons). From 1971 she was a full professor at the University of Wisconsin , where she had previously been a part-time lecturer since her husband became a professor there in 1959 (people had a guilty conscience there, as she had actually been professorial and professorial duties for many years qualified scientist). While this was an analyst, Ellen Rudin studied topology.

Rudin is known for constructing counterexamples in topology, e.g. B. Their construction of a Dowker space (Fundamenta Mathematica 1971, Clifford Hugh Dowker had suspected in 1951 that there are no such spaces). In 1986 she and others proved Kiiti Morita's first conjecture about normal rooms and a special case of the second Morita conjecture. In 2001 she proved a conjecture made by Nikiel.

It had the Erdős number 1 because she published with Paul Erdős in 1975 .

From 1980 to 1981 she was Vice President of the American Mathematical Society . In 1984 she was a Noether Lecturer . She is an honorary member of the Hungarian Academy of Sciences (1995), a fellow of the American Mathematical Society and since 1991 a member of the American Academy of Arts and Sciences . In 1974 she was invited speaker at the International Congress of Mathematicians in Vancouver (The normality of products).
