Why Brouwer Was Justified in his Objection to Hilbert's Unqualified Interpretation of Quantification
Abstract We define a finitary model of firstorder Peano Arithmetic in which quantification is interpreted constructively in terms of Turingcomputability, and show that it is incons...

A Finitary Model of Peano Arithmetic
We define a finitary model of first-order Peano Arithmetic in which satisfaction and quantification are interpreted constructively in terms of Turing-computability.

A standard model of Peano arithmetic with no conservative elementary extension
The principal result of this paper answers a long-standing question in the model theory of arithmetic [KS, Question 7] by showing that there exists an uncountable arithmetically cl...

Definability of Initial Segments
In any nonstandard model of Peano arithmetic, the standard part is not first order definable. But we show that in some model the standard part is definable as the unique solution ...
