Topic: 

Sharp bounds for the joins problem, an exposition cont'd

Description: 

In this second part of our exposition on the joints problem we showcase Yu and Zhao’s `Joints tightened’. This exciting application of the polynomial method has resulted in a rare occurrence in incidence geometry; the exact constant has been determined, i.e. the upper and lower bounds match up to a multiplicative 1+o(1) factor. Their (not
long) proof will be discussed in detail, and the key new ideas will be highlighted.
