Há 2 dias · Since the 1970s, the subject has been shaped decisively by Saharon Shelah's stability theory. Compared to other areas of mathematical logic such as proof theory, model theory is often less concerned with formal rigour and closer in spirit to classical mathematics.
6 de jun. de 2024 · Como parte de este trabajo proponemos, basados en [5], una prueba simplificada del Teorema de Compacidad de Shelah para grupos abelianos. Supported on P. Eklof's work [4], we present a complete proof of the independence of Whitehead's Problem for abelian groups of arbitrary cardinality.

17 de jun. de 2024 · was open for almost 20 years until Saharon Shelah [She00] found a negative solution in the year 2000. For this, he constructed a finite-support iteration using partial random forcing and sequences of finitely additive measures (fams) on P(ω) to preserve a witness of cov(N) without any restriction to the cofinality of its size.
