Edmond Bonan



Edmond Bonan (born 27 January 1937 in Haifa, Mandatory Palestine) is a French mathematician, known particularly for his work on special holonomy. Although not a single example of G2 manifold or Spin(7) manifold had been discovered until thirty years later, Edmond Bonan nonetheless  made a useful contribution by showing  in 1966,  that such  manifolds  would carry at least a  parallel 4-form,  and would necessarily be Ricci-flat, propelling them as candidates for string theory.

Biography
After completing his undergraduate studies at the École polytechnique, Bonan went on to write his 1967  University of Paris doctoral dissertation in Differential geometry under the supervision of  André Lichnerowicz. From 1968 to 1997, he held the post of lecturer and then professor at the University of Picardie Jules Verne in Amiens, where he currently holds the title of professor emeritus. Early in his career, from 1969 to 1981, he also lectured at the École Polytechnique.
