Talk:Descriptive set theory

Section Projective Sets

At the end of the section on Projective Sets, one suddenly starts talking about objects such as $L$ and ${\mathcal {P}}(\omega )$. However, these have not been defined. The last two paragraphs of the section are of a completely different level than the more introductory paragraphs that precede them. Nmdwolf (talk) 16:54, 12 December 2023 (UTC)

This article: 1.] introduces far too many unexplained advanced Set Theory symbols and concepts for it to be immediately comprehensible to most likely readers, and 2.] does not provide any explanation for what first motivated this research area, i.e. why this specialized area was seen by Set Theorists of the 1930s to be needed and what specific things they hoped it might accomplish. 23 October 2024 7:40 A.M.
