First order arithmetic
Many of the first order theories described above can be extended to complete recursively enumerable consistent theories. This is no longer true for most of the following theories; they can usually encode both multiplication and addition of natural numbers, and this gives them enough power to encode themselves, which implies that Gödel's incompleteness theorem applies and the theories can no longer be both complete and recursively enumerable (unless they are inconsist… WebMore Definitions of First Order.

WebThe aim of the book by Hajek and Pudlak is to cover some of the most important results in the study of a first order theory of the natural numbers, called Peano arithmetic and its fragments (subtheories). The field is quite active, but only a small part of the results has been covered in monographs. This book is divided into three parts.
WebJun 5, 2012 · This chapter explains the induction axioms we need to add, working up to the key theory PA, first-order Peano Arithmetic. Induction and the Induction Schema (a) In informal argumentation, we frequently appeal to the following principle of mathematical induction in order to prove general claims: Suppose (i) 0 has the numerical property P. WebWikipedia describes the first-order vs. second-order logic as follows: First-order logic uses only variables that range over individuals (elements of the domain of discourse); second-order logic has these variables as well as additional variables that range over sets of individuals. It gives ∀ P ∀ x ( x ∈ P ∨ x ∉ P) as an SO-logic ...
