Phase transitions for Gödel incompleteness

Andreas Weiermann
2009 Annals of Pure and Applied Logic  
For these independence principles we classify (as a part of a general research program) their phase transitions, i.e. we classify exactly the bounding conditions which lead from provability to unprovability  ...  As Gödel numbering for ordinals we choose the one which is induced naturally from Gödel's coding of finite sequences from his classical 1931 paper on his incompleteness results.  ...  The author also thanks the John Templeton foundation for supporting generously his phase transition project via the ''Exploring the infinite initiative''.  ...

Phase transitions in logic and combinatorics

Andreas Weiermann
2005 Expositions of Current Mathematics  
We try to explain our intuition about the nature of phase transition results under discussion.  ...  The resulting phase transitions from provability to unprovability are interesting from the foundational as well as from the mathematical point of view.  ...  Phase transitions and Gödel incompleteness The phase transition phenomenon is familiar from statistical physics, [8] , but also from percolation [17] , random graphs [3, 19] and computational complexity  ...

RETHINKING SPATIOTEMPORAL EXTENSION: HUSSERL'S CONTRIBUTION TO THE DEBATE ON THE CONTINUUM HYPOTHESIS

2018 Horizon: Fenomenologičeskie Issledovaniâ  
This is the case, for instance, for Weyl and Gödel himself, even if both of them gradually abandoned phenomenology for, respectively, constructivism/predicativism and Platonism.  ...  Although this latter is widespread among mathematicians, a few of them still think that the continuum conjecture is relevant for a philosophical foundation of set theory and, in general, for a scientific  ...  Among others, this is the case for J. Klein, H. Weyl, and K. Gödel.  ...

The Genius of Alan Turing: The Computing Classical Model

2013 International Journal of Machine Learning and Computing  
There are some variations in the model of a Turing machine, for example where one slides only to the right or ones possessing 5-tuple transitions basic states, instead of the classical 4-tuple transitions  ...  We aim to trace back the constituent phases of this convolution, by presenting at last a panoptical and functional plane of the computus realization, which has, by the passage from incompleteness to effective  ...

Metaphysics and mathematics: Perspectives on reality

The formalist approach to establish mathematical proof was found to be inconclusive: Gödel showed that there existed true propositions that could not be proved to be true within the natural number universe  ...  This result weighed heavily on proposals in the mid-20th century for digital models of the universe, inspired by the emergence of the programmable digital computer, giving rise to the branch of philosophy  ...  The technology is at present in an exploratory phase with realisation of a full-scale quantum computer somewhere in the future. not suffer the Gödel incompleteness properties.  ...

Undecidability everywhere? [article]

Karl Svozil
1995 arXiv   pre-print
Gödel [22] as well as Turing [62] used "the liar" [5] for their incompleteness theorems. Gödel was well aware of the fact that almost any classical paradox might do as well.  ...  Gödel, for instance, proved his incompleteness theorems as he succeeded to properly code a (generic) theory about arithmetic within arithmetic.  ...
