Education and career
Hanner earned his Ph.D. from Stockholm University in 1952.[5] He was a professor at the University of Gothenburg from 1963 to 1989.[6]
Contributions
In a 1956 paper,
Other contributions of Hanner include (with Hans Rådström) improving Werner Fenchel's version of Carathéodory's lemma,[12][13] contributing to The Official Encyclopedia of Bridge, and doing early work on combinatorial game theory and the mathematics of the board game Go.[14][15][16] One of the many proofs of the Pythagorean theorem based on the Pythagorean tiling is sometimes called "Olof Hanner's Jigsaw Puzzle".[17]
