Set Theory, Requirements, Witnesses,This is a very brief introduction to infinite cardinals. Our main interest here is in “requirements” and in “witnesses,” which are key concepts throughout this book.愤慨点吧 发表于 2025-3-25 09:35:51

,Length of Agreement (Sacks Splitting Theorem),Suppose that we are given a c.e.n. set ., and we wish to construct a c.e.n. set . having certain properties, including .. The length of agreement method, introduced here, is a way to do this.上流社会 发表于 2025-3-26 14:17:02

,A Tree of Guesses (Weak Thickness Lemma),The priority tree, which we call a “tree of guesses,” is introduced, and used for a construction involving infinite injury. The associated concept of “.-believability” is employed.
