Pure Maths Colloquium: Approximation by algebraic numbers
5 November 2012 16:00 in CM221
Quantifying the proximity of algebraic numbers to transcendental numbers represents a significant research area in the theory of Diophantine approximation. In this talk I will give a brief overview of the area including some latest developments. In particular, I will touch the recent Cantor sets technique of Badzihin and Velani and how it led to a solution of Bugeaud's problem regarding the existence of transcendental numbers badly approximable by algebraic numbers.
