AI visual note: The image shows page 36 of a paper containing Section 7.2 ("An explicit family without a choice function") and Lemma 7.4, which states: "In ZF, if a set A is not wellorderable, then P(A)\{∅} has no choice function." The proof proceeds by contradiction, using transfinite recursion on the Hartogs ordinal of A to construct an injection into A, thereby well-ordering it.
