This page provides a means for authors to have their papers made available for open inspection and feedback. All contributions are as supplied by the author, and are not peer-reviewed. Constructive feedback is encouraged, and should be sent direct to the relevant author, or posted to the companion discussion group, https://groups.io/g/UnsolvedProblems/topics,where questions can be asked and any of the problems or potential solutions discussed. If you wish to have a contribution published here, please read the FAQ, and then contact me.
