Solution to century-old math problem could predict transmission of infectious diseases

Science Daily  May 29, 2020 The diffusion equation models random movement and is one of the fundamental equations of physics. The analytic solution of the diffusion equation in finite domains, when time and space is continuous, has been known for a long time. However, the diffusion equation in finite space was not solved until now. Researchers in the UK used Chebyshev polynomials, and the method of images which is used to tackle electrostatic problems to construct the solution to the discrete diffusion equation in higher dimension from the one in lower dimensions. The solution could be used to accurately predict […]

‘Amazing’ Math Bridge Extended Beyond Fermat’s Last Theorem

Quanta Magazine  April 6, 2020 An international team of researchers (USA- Princeton, UK) came up with proof of Fermat’s Last Theorem tackling the theorem indirectly by means of an enormous bridge that mathematicians had conjectured should exist between two distant continents in the mathematical world. The proof boiled down to establishing this bridge between just two little plots of land on the two continents. The full bridge would offer mathematicians the hope of illuminating vast swaths of mathematics by passing concepts back and forth across it. Many problems, including Fermat’s Last Theorem, seem difficult on one side of the bridge, […]
