What: Week 3 Talk When: Thursday 17 August, 1 pm - 2 pm Where: New Law 024 Abstract: Everybody knows that nobody can solve the quintic. Indeed it’s a well known hard theorem, the high point of a full-semester course on Galois theory, often taken in one’s 3rd or 4th year of university mathematics. Abel-Ruffini Theorem. In this talk, we will explore an accessible proof of this famous theorem using basic and easily understandable topology. The level of content should be accessible for most undergraduates in mathematics.
