Mathematical analysis of memristor through fractal‐fractional differential operators: A numerical study

open access: yesMathematical methods in the applied sciences, 2020
The newly generalized energy storage component, namely, memristor, which is a fundamental circuit element so called universal charge‐controlled mem‐element, is proposed for controlling the analysis and coexisting attractors.

On Local Time for Telegraph Processes

open access: yesMathematics, 2023
The article consists of an introduction into the theory of passage times associated with telegraph processes. Local time for the telegraph process is defined and analysed. We provide some limited results for telegraphic local times.

Analytic Resolving Families for Equations with the Dzhrbashyan–Nersesyan Fractional Derivative

open access: yesFractal and Fractional, 2022
In this paper, a criterion for generating an analytic family of operators, which resolves a linear equation solved with respect to the Dzhrbashyan–Nersesyan fractional derivative, via a linear closed operator is obtained.

Mathematical Analysis of Chemical Reaction Systems [PDF]

open access: yes, 2018
The use of mathematical methods for the analysis of chemical reaction systems has a very long history, and involves many types of models: deterministic versus stochastic, continuous versus discrete, and homogeneous versus spatially distributed.

Disentangling the Information in Species Interaction Networks

open access: yesEntropy, 2021
Shannon’s entropy measure is a popular means for quantifying ecological diversity. We explore how one can use information-theoretic measures (that are often called indices in ecology) on joint ensembles to study the diversity of species interaction ...
