On Generalizing Kolmogorov

Richard Dietz
2010 Notre Dame Journal of Formal Logic  
Weatherson's generalized notion of probability can hardly be regarded as adequate, as the example of supervaluationist logic shows.  ...  It is suggested that for supervaluationist logic, the third option is the most attractive one, for (unlike the other options) it preserves respect for single-premise entailment.  ...  If one takes respect for logic, and general additivity as 'essential' features of any notion of probability, trivially, one ends up with generalized probability.  ...

Magnetic-Field Generation in Kolmogorov Turbulence

Stanislav Boldyrev, Fausto Cattaneo
2004 Physical Review Letters  
For the Kolmogorov velocity field, this gives H k ∝ k −7/3 .  ...  To address magnetic energy on larger scales we have to understand how the magnetic field is generated in the inertial interval of fluid turbulence (the interval of scales much smaller than the external  ...

Generic image similarity based on Kolmogorov complexity

Nima Nikvand, Zhou Wang
2010 2010 IEEE International Conference on Image Processing  
The theory of Kolmogorov complexity and the related normalized information distance (NID) measure provide an attractive theoretic framework for generic image similarity that is applicable to any scenario  ...  While this is appealing, the difficulty lies in the implementation due to the non-computable nature of Kolmogorov complexity.  ...  Moreover, due to their focuses on specific applications, the generic property of NID was not fully exploited.  ...

On the Connections of Generalized Entropies With Shannon and Kolmogorov–Sinai Entropies

Fryderyk Falniowski
2014 Entropy  
Under mild assumptions on this function we show that this isomorphism invariant is linearly dependent on the Kolmogorov-Sinai entropy.  ...  We consider the concept of generalized measure-theoretic entropy, where instead of the Shannon entropy function we consider an arbitrary concave function defined on the unit interval, vanishing in the  ...  on every generator of the σ-algebra Σ.  ...

Operators on superspaces and generalizations of the Gelfand–Kolmogorov theorem

H. M. Khudaverdian, Th. Th. Voronov, Piotr Kielanowski, Anatol Odzijewicz, Martin Schlichenmeier, Theodore Voronov
2007 AIP Conference Proceedings  
We give a simplification and a further extension of this theory, which is based, rather unexpectedly, on results from super linear lgebra.  ...  Gelfand and Kolmogorov in 1939 proved that a compact Hausdorff topological space X can be canonically embedded into the infinite-dimensional vector space C(X)^* , the dual space of the algebra of continuous  ...  Recently Buchstaber and Rees have suggested a generalization of the Gelfand-Kolmogorov theorem based on their notion of an n-homomorphism or 'Frobenius n-homomorphism'.  ...

Nucleation and growth in one dimension. I. The generalized Kolmogorov-Johnson-Mehl-Avrami model

Suckjoon Jun, Haiyang Zhang, John Bechhoefer
2005 Physical Review E  
Motivated by a recent application of the Kolmogorov-Johnson-Mehl-Avrami (KJMA) model to the study of DNA replication, we consider the one-dimensional version of this model.  ...  We generalize previous work to the case where the nucleation rate is an arbitrary function I(t) and obtain analytical results for the time-dependent distributions of various quantities (such as the island  ...  ACKNOWLEDGMENTS We thank Tom Chou, Massimo Fanfoni, Govind Menon, Nick Rhind, and Ken Sekimoto, Massimo Tomellini for helpful comments and discussions on 1D nucleation-and-growth models.  ...

Thermostatistics based on Kolmogorov–Nagumo averages: unifying framework for extensive and nonextensive generalizations

Marek Czachor, Jan Naudts
2002 Physics Letters A  
We use this correspondence to generalize thermostatistics to a large class of Kolmogorov-Nagumo means and suitably adapted definitions of entropy.  ...  We show that extensive thermostatistics based on Renyi entropy and Kolmogorov-Nagumo averages can be expressed in terms of Tsallis non- extensive thermostatistics.  ...  One of the authors (M.C.) wishes to thank the NATO for a research fellowship enabling his stay at the Universiteit Antwerpen.  ...

On classical and quantal Kolmogorov entropies

J W Helton, M Tabor
1985 Journal of Physics A: Mathematical and General  
The construction of a quantal Kolmogorov entropy that tends to the classical Kolmogorov entropy in the limit h -t 0 is discussed.  ...  interesting illustration of a quantal definition of a statistical quantity not having the correct classical limit (a feature that by no means invalidates its usefulness) has been in the context of quantal Kolmogorov  ...  By contrast, generic Hamiltonians are non-integrable. Now the phase space has a most complicated structure of stable and unstable orbits pathologically intertwined.  ...
