The IBM Research|NYU|Columbia Theory Day is a semi-annual conference aimed to bring together people in New York Metropolitan area for one day of interaction and discussion. The Theory Day features several (usually 4-5) hour-long presentations by leading theoretical computer scientists about state-of-the-art advances in various areas. Some presentations give a survey of the latest advances in some area, while others may concentrate on a particular (often ground-breaking!) result. The meeting is free and open to everyone; in particular, students are encouraged to attend.
