In the interest of getting more content on this blog (and possibly inspiring students?), PTReview has decided to put an “Open Problem of the Month” feature. No problem is too big or too small, and even fuzzily defined open problems are game.
We would like these contributions to come from the community, instead of it being a mouthpiece for what the editors care for. If you want to contribute, send email to firstname.lastname@example.org (and/or contact one of Eric, Sesh, Sourav personally). We’re not too hung up on what format to use, but it would be nice to include a reference (if it exists) and history. The editors might iterate with you to make the final post.
