Summer Opportunity: Polymath Jr Research Experience for Undergraduates. The goal of this remote program is to provide opportunities to undergraduates who wish to explore research mathematics. The program consists of research projects on a wide variety of mathematical topics. Each project is guided by an active researcher with experience in undergraduate mentoring. All undergraduates who have experience with writing mathematical proofs are eligible. Part-time participation is also allowed; preference is given to students who will not have an undergraduate degree by July 2021.
