Poul Heegaard was a professor of mathematics at Copenhagen University 1910 - 1917 and at Christiania (later Oslo) University 1918 - 1941. Today he is best known for his contributions to the study of three-manifolds; in fact Heegaard splittings and Heegaard diagrams
Poul Heegaard (November 2 , 1871 - February 7 , 1948 ) was a Danish mathematician active in the field of topology . His 1898 thesis introduced a concept now called the Heegaard splitting of a 3-manifold . Heegaard's ideas allowed him to make a careful critique of work of Henri Poincaré . Poincaré had overlooked the possibility of the appearance of torsion in the homology groups of a space.
He later co-authored, with Max Dehn , a foundational article on combinatorial topology , in the form of an encyclopedia entry.
Heegaard studied mathematics at the University of Copenhagen , from 1889 to 1893 and following years of travelling, and teaching mathematics, he was appointed professor at University of Copenhagen in 1910.
Following a dispute with the faculty over, among other things, the hiring of Harald Bohr as professor at the University (Heegaard was against it); Heegaard accepted a professorship at Kristianssand in Norway , where he worked till his retirement in 1941
