On a rigorous definition of microscopic solutions of the Boltzmann–Enskog equation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
N. N. Bogolyubov discovered microscopic solutions of the Boltzmann–Enskog equation in kinetic theory of hard spheres. These solutions have the form of sums of the delta-functions and correspond to the exact microscopic dynamics. However, this was done at

On defining the generalized functions δα(z) and δn(x)

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
In a previous paper (see [5]), we applied a fixed δ-sequence and neutrix limit due to Van der Corput to give meaning to distributions δk and (δ′)k for k∈(0,1) and k=2,3,….

Mitochondrial Functioning ≠ General Intelligence [PDF]

open access: yesJournal of Intelligence, 2020
Geary puts forward an appealing argument for the consideration of mitochondrial functioning as a candidate for a formative g Geary (2019); it is also an ambitious argument [...]

On the Duality of Regular and Local Functions

open access: yesMathematics, 2017
In this paper, we relate Poisson’s summation formula to Heisenberg’s uncertainty principle. They both express Fourier dualities within the space of tempered distributions and these dualities are also inverse of each other.

Stochastic Equations and Equations for Probabilistic Characteristics of Processes with Damped Jumps

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
Processes such as shot noise are an adequate tool for modeling discontinuous random processes with a damping effect. Such processes arise in various fields of physics, technology and human activity, including the field of finance.

Generalized Trigonometric Functions [PDF]

open access: yesMathematics of Computation, 1964
is also that of all functions of the form (1 + x2)-2N-c+lQ(x) where Q is a polynomial of degree 4N 2 or lower, the conditions determining the above formula for any a and N are the same as those determining Harper's formula for (using "k" and "n" in the meaning given them in [1]) k = a + 2N -2, n = 2N.

Generating function for generalized function of two variables [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
In this paper we obtain a generating function for a generalized function of two variables. The result is very general in character and includes as particular cases some of the results recently given by Meijer [4], Carlitz [7] and Srivastava [5].

Concrete Generic Functionals [PDF]

open access: yes, 2003
Generic design is not only pertinent to programs, but a fortiori to declarative formalisms as well, and the ensuing generalizations often benefit programming. In the considered framework, generality is obtained by (re)defining traditionally non-functional objects uniformly as functions.

Increasing the spatial resolution of signals in optical systems

open access: yesКомпьютерная оптика, 2022
Reconstruction of the signal in the intervals between discrete values is of great importance in solving the problem of spatial superresolution in optical microscopy and digital holography.

Some concepts of generalized convex functions (I)

open access: yesJournal of Numerical Analysis and Approximation Theory, 2002
An extension of the concept of convex function is given in a very general framework provided by a set in which a general convexity for its subsets is defined.
