A note on connectedness in cartesian closed categories

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 20, Issue 1, Page 101-104, 1997., 1997
Primaxily working in the category of limit spaces and continuous maps we suggest a new concept of connectivity with application in all categories where function space objects satisfy natural exponential laws. In a separate Appendix we motivate the development of a homotopy theory for spaces of real‐valued continuous maps endowed with the structure of ...

Compactification of closed preordered spaces [PDF]

open access: yes, 2012
A topological preordered space admits a Hausdorff closed preorder compactification if and only if it is Tychonoff and the preorder is represented by the family of continuous isotone functions.

Probability-free relativistic kinetic theory of classical systems of charged particles

open access: yesJournal of Physics: Conference Series, 2020
In the complete system of equations of evolution of the classical system of charges and the electromagnetic field generated by them, the field variables are excluded. An exact closed relativistic non-Hamiltonian system of nonlocal kinetic equations, that

Direct Proofs of Order Independence [PDF]

open access: yes, 2011
We establish a generic result concerning order independence of a dominance relation on finite games. It allows us to draw conclusions about order independence of various dominance relations in a direct and simple way.Comment: 9 ...

Software Engineering and Complexity in Effective Algebraic Geometry [PDF]

open access: yes, 2012
We introduce the notion of a robust parameterized arithmetic circuit for the evaluation of algebraic families of multivariate polynomials. Based on this notion, we present a computation model, adapted to Scientific Computing, which captures all known ...

Dynamics of generation modes changes in magnetic field depending on the oscillation frequency of the α-effect suppression process by field energy in the αΩ-dynamo model

open access: yesВестник КРАУНЦ. Физико-математические науки, 2022
В статье рассматривается крупномасштабная модель αΩ-динамо в маломодовом приближении. Интенсивность α-эффекта регулируется процессом с эредитарными свойствами (), зависящим от энергии магнитного поля.

Bounds for the probability generating functional of a Gibbs point process

open access: yes, 2013
We derive explicit lower and upper bounds for the probability generating functional of a stationary locally stable Gibbs point process, which can be applied to summary statistics like the F function.
