Mathematical Sciences - Virtual Combinatorics Colloquium Hosted by the Northeast Combinatorics Network - "Points and Lines" by Vašek Chvátal

Thursday, October 25, 2018
3:00 pm to 4:00 pm


Floor/Room #: 

Speaker: Vašek Chvátal

Title: Points and Lines

Abstract: A set of n points in the Euclidean plane determines at least n distinct lines unless these n points are collinear. In 2006, Chen and Chvátalasked whether the same statement holds true in general metric spaces, where the line determined by points x and y is defined as the set consisting of x, y, and all points z such that one of the three points x, y, z lies between the other two. We will trace the curriculum vitae of the conjecture that it does hold true and point out related open problems.

Host a Local Viewing Party!
Campuses from around the Northeast will be logging in to the Zoom platform to watch these engaging lectures and to interact with the speakers in real time. Here are some suggestions for viewing party hosts:
•Arrange a room far in advance with a projection screen
•Advertise the talk to get faculty and students to attend together
•Offer snacks to entice students to attend
•Have a local faculty member give a mini pre-lecture introduction andengage in group discussion afterwards
