A Ukrainian mathematician who proved the best way to pack spheres in eight dimensions to take up the least space, and an Oxford expert who has solved conundrums in the spacing of prime numbers, are among the winners of the Fields medal, considered the equivalent of a Nobel prize for mathematics.
The winners of the prize, presented at the International Mathematical Union awards ceremony in Helsinki, have been announced as Prof James Maynard 35, from Oxford University, Prof Maryna Viazovska, 37, of the École polytechnique fédérale de Lausanne, Hugo Duminil-Copin, 36, of the University of Geneva and Institut des Hautes Études Scientifiques, and June Huh, 39, of Princeton University.
