Donald Solitaire

from Wikipedia, the free encyclopedia

Donald Moiseyevich Solitar (born September 5, 1932 in Brooklyn , † April 28, 2008 in Toronto ) was a Canadian-American mathematician.

Solitar graduated from Brooklyn College with a bachelor's degree in 1953 and Princeton University with a master's degree. He actually wanted to do a doctorate on group theory with Emil Artin in Princeton, but he no longer dealt with it and so he went instead to New York University , where he received his doctorate in 1958 with Wilhelm Magnus (On subgroup theorems). He had previously published with his fellow student Abraham Karrass on infinite groups and combinatorial group theory. From 1959 he taught at Adelphi University , where he led the National Science Foundation Summer Institute for High School Teachers with Karrass, and from 1968 at York University .

He dealt with combinatorial group theory and infinite groups. With Gilbert Baumslag he introduced tree lag solitar groups in 1962.

In 1982 he became a Fellow of the Royal Society of Canada .

Abraham Karrass (PhD thesis 1961, Adelphi University), who was also his fellow student in New York and who later worked closely with him, is one of his doctoral students.
