Minimum functional equation and some Pexider-type functional equation on any group

open access: yesAIMS Mathematics, 2021
We discuss the solution to the minimum functional equation $ \begin{align} \min \{\, \eta(xy^{-1}), \eta(xy) \, \} = \eta(x)\eta(y), \qquad x, y \in G, \end{align} $ for a real-valued function $ \eta: G \to \mathbb{R} $ defined on arbitrary ...

Functional extreme learning machine

open access: yesFrontiers in Computational Neuroscience, 2023
IntroductionExtreme learning machine (ELM) is a training algorithm for single hidden layer feedforward neural network (SLFN), which converges much faster than traditional methods and yields promising performance.

Counting Lattice Paths by Using Difference Equations with Non-constant Coefficients

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
The lattice paths can be counted by the virtue of their step vectors that are aligned to the positive octant. A path can go from one point to an infinite others if there is no restriction applied such that each point only has finitely many predecessors ...

The Role of Riemann’s Zeta Function in Mathematics and Physics †,‡

open access: yesUniverse, 2019
In particular, Riemann’s impact on mathematics and physics alike is demonstrated using methods originating from the theory of numbers and from quantum electrodynamics, i.e., from the behavior of an electron in a prescribed external electromagnetic ...

Analysis of a new skip list variant [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
For a skip list variant, introduced by Cho and Sahni, we analyse what is the analogue of horizontal plus vertical search cost in the original skip list model.

Discrete Integrals Based on Comonotonic Modularity

open access: yesAxioms, 2013
It is known that several discrete integrals, including the Choquet and Sugeno integrals, as well as some of their generalizations, are comonotonically modular functions.

Equating Schur functions

open access: yesThe European Physical Journal C, 2023
AbstractWe wonder if there is a way to make all Schur functions in all representations equal. This is impossible for fixed value of time variables, but can be achieved for averages. It appears that the corresponding measure is just Gaussian in times, which are all independent.

Analysis of a Class of Stochastic Animal Behavior Models under Specific Choice Preferences

open access: yesMathematics, 2022
The behavior of animals can be studied in two ways: experimentally, in labs or in the field, or theoretically, via modeling. Extensive research on animal behavior in probabilistic learning circumstances has produced findings that are consistent with so ...
