Nonstandard methods in combinatorial number theory

August 14 to August 18, 2017

at the

American Institute of Mathematics, San Jose, California

organized by

Mauro Di Nasso, Isaac Goldbring, and Martino Lupini

Original Announcement

This workshop hopes to further develop the use of nonstandard methods in combinatorial number theory and Ramsey theory. For example, recently nonstandard methods have proven useful in problems about configurations of sumsets in sets of positive density as well as partition regularity of equations. Our aim is to continue to explore these and other directions leading to a greater understanding of the role that nonstandard methods could play in this area of combinatorics. Examples of specific questions include:
