Chinese maths star Wang Hong solves ‘infamous' geometry problem
Chinese mathematician Wang Hong has solved an 'infamous' geometry problem called the Kakeya conjecture within three dimensions. Advertisement It is considered a breakthrough that could have implications for imaging, data processing, cryptography and wireless communication. Wang – who was born in the southern Chinese city of Guilin and graduated from Peking University – is an associate professor at the New York University Courant Institute of Mathematical Sciences. Wang and her collaborator Joshua Zahl, from The University of British Columbia, presented their milestone proof in a preprint paper that has not undergone peer review on the open-access repository arXiv on February 24. Australian-American mathematician Terence Tao, the 'Mozart of maths' and winner of the 2006 Fields Medal – one of the highest awards in mathematics – took note of the paper online soon after.
