Ukrainian mathematician Maryna Viazovska has been named as one of four recipients of the prestigious Fields Medal, which is often described a the Nobel prize in mathematics

France's Hugo Duminil-Copin, US-based June Huh and Britain's James Maynard were also awarded the medals at a ceremony in Helsinki on Tuesday, the International Mathematical Union jury said.

The Fields medal recognises "outstanding mathematical achievement" by under-40s and is awarded once every four years.

The ceremony was part of the International Congress of Mathematicians, which was initially scheduled to be held in Saint Petersburg but was moved online due to the conflict in Ukraine. The award ceremony took place in Finland.

Viazovska, who holds the chair in number theory at the Swiss Federal Institute of Technology Lausanne, is only the second woman to win the prize in its over 80-year history.

The International Congress of Mathematicians said Viazovska was being honoured for her work on the densest packing of identical spheres in eight dimensions.

Sphere packing problem

Viazovska was born in 1984 in Ukraine, then still part of the Soviet Union, and has been a professor at the Ecole Polytechnique Federale de Lausanne in Switzerland since 2017.

The "sphere packing problem" that granted her the prize dates back to the 16th century, when the question of how cannonballs should be stacked to achieve the densest possible solution was poised.

The first woman to win the prize was Maryam Mirzakhani in 2014, an Iranian-born mathematician who died three years later in 2017 after a battle with cancer.

Duminil-Copin, born in France in 1985, is a professor at the Institut des Hautes Etudes Scientifiques, focusing on the mathematical branch of statistical physics.

Carlos Kenig, President of the International Mathematical Union, said Duminil-Copin was honoured for solving "long-standing problems in the probabilistic theory of phase transitions", which according to the jury has opened up several new research directions.

Maynard, 35, is a professor at the University of Oxford in the United Kingdom and received the medal "for contributions to analytic number theory, which have led to major advances in the understanding in the structure of prime numbers and in Diophantine approximation", Kenig said.

"His work is highly ingenious, often leading to surprising breakthroughs on important problems that seemed to be inaccessible by current techniques," the union said in statement.

June Huh, 39, a professor at Princeton University in the United States, was given the award for "transforming" the field of geometric combinatorics, "using methods of Hodge theory, tropical geometry, and singularity theory", the jury said.
