Welcome to *AimPL: the American Institute of Mathematics Problem
Lists*. This website provides a mechanism for creating and maintaining
up-to-date lists of unsolved problems in research mathematics.

Users can read precise statements of open problems, along with accompanying remarks, as well as pose new problems and add new remarks. Problem lists are overseen by an editorial board who approves all modifications to the list.

We invite you to explore open problems in any area of interest. You can browse and add remarks anonymously, or register and log in to have more options. Please send questions or comments to problemlists@aimath.org.
