Interactive Talk on Combinatorics with Po-Shen Loh
When Bare Hands Fail
On the Monday 22nd July, the G-Research Distinguished Speaker Series will return with an interactive talk from Po-Shen Loh, in celebration of G-Research’s gold sponsorship of the IMO 2019. Hosted at the Royal College of Physicians, the talk will run from 6pm and will end with a Q&A session followed by a drinks and canapé reception.
Many people associate Combinatorics with elementary, ad-hoc arguments that are understandable by a primary-school child. Indeed, that is one of the aspects which makes Combinatorics fascinating: that a solution composed of a chain of (albeit fantastically clever) bare-hands steps can be so difficult to find, yet is easy to follow once it is found. However, this is not universally true, and indeed, many modern combinatorial problems are solved by importing theorems and techniques from other branches of mathematics, such as algebra, probability, or even topology.
In this interactive talk, entitled ‘When Bare Hands Fail’, we will use one of the most difficult problems from a recent USA Mathematical Olympiad exam to illustrate some of these connections. Po-Shen will also comment on Math Olympiads in general, as well as some particulars of the USA’s recent Olympiad strategy, which has been to move away from elementary Olympiad mathematics, in favour of drawing connections to mathematics beyond the Olympiad curriculum.
