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 ...

On a credit oscillatory system with the inclusion of stick-slip

open access: yesE3S Web of Conferences, 2016
The work was a mathematical model that describes the effect of the sliding attachment (stick-slip), taking into account hereditarity. This model can be regarded as a mechanical model of earthquake preparation.

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.

Radon transport model into a porous ground layer of finite capacity

open access: yesE3S Web of Conferences, 2017
The model of radon transfer is considered in a porous ground layer of finite power. With the help of the Laplace integral transformation, a numerical solution of this model is obtained which is based on the construction of a generalized quadrature ...

DETERMINISTIC FACTOR ANALYSIS: METHODS OF INTEGRO-DIFFERENTIATION OF NON-INTEGRAL ORDER

open access: yesRussian Journal of Economics and Law, 2016
Objective: to summarize the methods of deterministic factor economic analysis, namely the differential calculus and the integral method. Methods: mathematical methods for integro-differentiation of non-integral order, the theory of derivatives and ...

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 ...

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 ...

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.
