Ramsey Theory:
from the happy-ending theorem to Graham’s number

Thursdays at 6:30 pm ET (New York)
May 13, May 20, and June 3

Appropriate for ages 14 and up


In honor of Ronald Graham, who passed away last summer, Paul Zeitz presents a three-part mini-course that explores Ramsey Theory, the study of order within randomness — and the mathematical glue of the long friendship between Graham and the eccentric genius Paul Erdős.

While registration for standalone sessions is allowed and catch-up notes will be provided, attending all three sessions is strongly encouraged for the best possible experience.  Note that no refunds will be offered.
