Há 4 dias · The axiomatic approach, introduced by Ernst Zermelo and Abraham Fraenkel, provided a rigorous and systematic way to formulate and study the foundations of mathematics. It also introduced the concept of the Axiom of Choice, which stated that given a collection of non-empty sets, it is possible to choose exactly one element from each set, even if the collection is infinite.
Há 5 dias · We discuss the philosophical significance of classical and more recent results in the metamathematics of set theory: the Gödel-Cohen independence theorem of the Continuum Hypothesis (CH) from first-order set theory; Zermelo's quasi-categoricity result characterizing models of second-order set theory and Lavine's improvement thereof ...
Há 1 dia · To address these challenges, we propose a method for improving prediction performance when incorporating similar data from external subgroups, e.g., other medical centers, for building a model for the target subgroup of interest. Specifically, observations of external subgroups are assigned weights that include individual and subgroup-specific ...

Há 5 dias · Large cardinals are certain types of infinite cardinal numbers that possess special properties and consistency strength beyond those of the standard axioms of set theory, such as Zermelo-Fraenkel set theory (ZF) or Zermelo-Fraenkel set theory with the axiom of choice (ZFC).
Há 3 dias · This can be reasoned out as follows. Suppose A was born on a Tuesday. Then A would have concluded that B was born on a Wednesday because A knew that B was not born on a Monday. However, if this ...
