Title: Open collaborative mathematics over the Internet - three examples

Speaker: ** Gil Kalai**, Hebrew University and Yale University

Date: Thursday, January 31, 2013 5:00pm

Location: Hill Center, Room 705, Rutgers University, Busch Campus, Piscataway, NJ

Abstract:

I will discuss several examples of recent Internet research oriented math activities:

1) Polymath5 - Erdos discrepancy problem.

Background: please look at this MO problem
http://mathoverflow.net/questions/105383/the-behavior-of-a-certain-greedy-algorithm-for-erds-discrepancy-problem
(and the blog post linked there.)

2) Mobius randomness over blogs and MathOverflow.

We will talk only briefly about it. Here is one link:
MO posts: http://mathoverflow.net/questions/57543/walsh-fourier-transform-of-the-mobius-function

3) My debate with Aram Harrow on the feasibility of quantum computers.

It took place over the blog "Goedel's lost letter and NP=P" (The first post the last post )

I will try to give a little taste of the mathematical problems/issues and a little taste of this way of "doing mathematics".

To get in the mood for this brave new world, some of Dr. Z's rules will not apply (as far as I am concerned):
You can bring laptops tablets smartphones and paper to the lecture and do with them whatever you want. Comments and interuptions are welcome.
You are most welcome to look at the links here in the abstract before the lecture, after the lecture, during the lecture or even instead of the lecture.
