Gabriel Andrew Dirac (13 March 1925 – 20 July 1984) was a Hungarian-British mathematician who mainly worked in graph theory. [1] He served as Erasmus Smith's Professor of Mathematics at Trinity College Dublin from 1964 to 1966. [2] In 1952, he gave a sufficient condition for a graph to contain a Hamiltonian circuit. The previous year, he conjectured that n points in the plane, not all collinear, must span at least two-point lines, where is the largest integer not exceeding . This conjecture was proven true when n is sufficiently large by Green and Tao in 2012. [3]
Dirac started his studies at St John's College, Cambridge in 1942, but in that same year, the war saw him serving in the aircraft industry. [1] He received his MA in 1949, and moved to the University of London, getting his Ph.D. "On the Colouring of Graphs: Combinatorial topology of Linear Complexes" there under Richard Rado. [4]
Dirac's main academic positions were at the King's College London (1948-1954), University of Toronto (1952-1953), University of Vienna (1954-1958), University of Hamburg (1958-1963), Trinity College Dublin ( Erasmus Smith's Professor of Mathematics, 1964-1966), University of Wales at Swansea (1967-1970), and Aarhus University (1970-1984). [1]
He was born Balázs Gábor in Budapest, to Richárd Balázs, a military officer and businessman, and Margit "Manci" Wigner (sister of Eugene Wigner). [5] When his mother married Paul Dirac in 1937, he and his sister resettled in England and were formally adopted, changing their family name to Dirac. [6] He married Rosemari Dirac and they had four children together: Meike, Barbara, Holger and Annette. [7]
