Description

In this talk, we will look at recent advancements in Euclidean Ramsey Theory. In particular, we will discuss results on colourings that avoid monochromatic 'progressions' -- finite sets of evenly spaced collinear points. We will discuss constructions of geometric graphs and a well-studied method of space colouring known as spherical colouring.

 

This talk is based on joint work with Gabriel Currier and Chi Hoi Yip.
