THE REVERSE MATHEMATICS OF CAC FOR TREES
نویسندگان
چکیده
is the statement asserting that any infinite subtree of has an path or antichain. In this paper, we study computational strength theorem from a reverse mathematical viewpoint. We prove robust, is, there exist several characterizations, some which already appear in literature, namely, introduced by Dorais et al. [8], and where tree antichain Conidis [6]. show computationally very weak, it admits probabilistic solutions.

Reverse mathematics, computability, and partitions of trees
Weexamine the reversemathematics and computability theory of a formofRamsey’s theorem in which the linear n-tuples of a binary tree are colored. Let 2<N denote the full binary tree of height!. We identify nodes of the tree with finite sequences of zeros and ones, and refer to any subset of the nodes as a subtree. For positive integers n, let [2<N]n denote the set of all linearly ordered n-tuple...

Reverse-engineering Reverse Mathematics
An important open problem in Reverse Mathematics ([16, 25]) is the reduction of the first-order strength of the base theory from IΣ1 to I∆0 + exp. The system ERNA, a version of Nonstandard Analysis based on the system I∆0 + exp, provides a partial solution to this problem. Indeed, Weak König’s lemma and many of its equivalent formulations from Reverse Mathematics can be ‘pushed down’ into ERNA,...

15 صفحه اولReverse Mathematics
In math we typically assume a set of axioms to prove a theorem. In reverse mathematics, the premise is reversed: we start with a theorem and try to determine the minimal axiomatic system required to prove the theorem (over a weak base system). This produces interesting results, as it can be shown that theorems from different fields of math such as group theory and analysis are in fact equivalen...
