Tangencies, Incidences, and Unit Distances

Joshua Zahl, University of British Columbia

Date and time: 11:30am, Friday, May 3, 2019

Place: Baruch College (55 Lexington Ave), Room 6-215

Note the unusual time and location!!

In this talk I will discuss some recent developments in incidence geometry related to counting the number of tangencies between collections of circles in the plane, the unit distance problem in three dimensions, and some estimates from harmonic analysis.
