This is a place that’s meant to store information about open problems in homotopy theory and connected subjects, and (to the extent possible) some information about what their background is and what has been tried.
If you have stumbled upon this at random, you should feel free to read around, or make alterations if you feel that some further information would be useful. We are actively soliciting problems from those in the field; if we have not explicitly asked you, we are still interested.
