Q. You have asked about recursively denumerable sets on the SeT page. I am not sure if you are questioning:
- 1). the existence of such a sets.
- 2). whether such sets are well-defined
- AND MORE IMPORTANT
- 1). If you are tryimg to illicit more content, please feel free to add content to the page.
- 2). If you are referring to the paradoxes resulting from looking at sets like X = {x: x is a set}, a more limited problem, Russell's Paradox is on the SetTheory page.
In conclusion, perhaps an example of such a set would help. RoseParks
