Past Projects

 

The Mathematics at SUMRY

SUMRY research projects in recent years have spanned a range of topics that have included the chip-firing games, combinatorics of integer partitions, game theory, geometry of moduli spaces, number theory, probability theory, tropical geometry, dynamics, and various other questions number theory, combinatorics, and algebraic geometry. The problems are important open questions, and are carefully chosen by the SUMRY team to be accessible for a undergraduate group to make progress in ten weeks, but also of broader interest to the mathematical community. As a result, the questions that we pursue tend to be close to the advisor’s research area, and vary from year to year, based on the team. Great care is taken in matching participants with both teammates and projects.

You can find more information about the projects by taking a look at the titles, papers, and slides from past years’ projects below.

SUMRY 2017

During the summer of 2017, we had 6 student research projects. All of these groups presented their work at MAA’s Mathfest in Chicago, IL, where 4 of 6 of our groups won “Outstanding Presentation” awards. Four of the groups also presented their work at the Young Mathematicians’ Conference in Columbus, OH. Here are the projects from 2017. Papers related to these projects are in preparation and will be added in due course. 


SUMRY 2016

During the summer of 2016, we had 6 student research projects. All of these groups presented their work at MAA’s Mathfest in Columbus, OH, where a number of our students won “Outstanding Presentation” awards. Four of the groups also presented their work at the REU Mini-Symposium, hosted by Williams College. Here are the projects from 2016. Papers related to these projects are in preparation and will be added in due course.
