# Incidences of lines in 3-space

Tuesday, April 8, 2014 -

4:30pm to 6:00pm

Let L be a set of m distinct lines 3-space. Elekes and Sharir conjectured that, aside from some obvious counter examples, the lines in L have at most C m^{3/2} intersection points. This was proved by Guth and Katz. I will explain the proof with some improvements that make the constant C effective.
