On Friday the 9th of February 2018, Rachel Newton (University of Reading) will be visiting Lincoln and giving a seminar at 2.30pm in INB 3305. All are welcome to attend. Her talk will be on “Counting failures of a local-glocal principle” and her talk abstract is as follows: “The search for rational solutions to polynomial equations is ongoing for more than 4000 years. Modern approaches try to piece together ‘local’ information to decide whether a polynomial equation has a ‘global’ (i.e. rational) solution. I will describe this approach and its limitations, with the aim of quantifying how often the local-global method fails within families of polynomial equations arising from the norm map between fields, as seen in Galois theory. This is joint work with Tim Browning.”
