German Idealism and the Origins of Pure Mathematics: Riemann, Dedekind, Cantor [PDF]

open access: yesJournal of Philosophical Investigations, 2021
When it comes to the relation of modern mathematics and philosophy, most people tend to think of the three major schools of thought—i.e. logicism, formalism, and intuitionism—that emerged as profound researches on the foundations and nature of ...

Mathematical Modeling of Wax Deposition in Field-Scale Crude Oil Pipeline Systems

open access: yesJournal of Applied Mathematics, 2022
The formation of solid wax crystals, which interlock and form a gel-like layer on the inner wall of the crude oil pipeline, influences the transportation of waxy crude oil. The deposited layer grows continuously and hardens during the oil transportation,

Hydromagnetic Non-Newtonian Fluid Flow in a Convergent Conduit

open access: yesJournal of Applied Mathematics, 2022
In the present study, a hydromagnetic non-Newtonian (dilatant) fluid flow in a convergent conduit, in the presence of a variable transverse magnetic field, has been investigated.

Computing some Laplacian Coefficients of Forests

open access: yesJournal of Applied Mathematics, 2022
Let G be a finite simple graph with Laplacian polynomial ψG,λ=∑k=0n−1n−kckλk. In an earlier paper, the coefficients cn−4 and cn−5 for forests with respect to some degree-based graph invariants were computed. The aim of this paper is to continue this work

hα-Open Sets in Topological Spaces [PDF]

open access: yesمجلة التربية والعلم, 2022
In our work we introduced a new type of open sets is defined as follows: If for each set that is not empty M in X, M≠X and M ∈τ^∝such that A ⊆ int(A∪M). then A in (X,τ) is named h∝-open set. We also go through the relationship between h∝- open sets and a

An Application of the t-Extension of the p-Fibonacci Pascal Matrix in Coding Theory

open access: yesAdvances in Mathematical Physics, 2022
We consider the t-extension of the p-Fibonacci Pascal matrix. First, we study the k-th power of the t-extension of the p-Fibonacci lower and upper triangular Pascal matrix.

A (Discrete) Homotopy Theory for Geometric Spaces

open access: yesJournal of Mathematics, 2023
We define the concepts of homotopy and fundamental group for geometric spaces as a generalization of metric spaces, digital spaces, and graphs; then, we compare them with corresponding concepts in these spaces.

Cohen Positive Strongly p-Summing and p-Dominated m-Homogeneous Polynomials

open access: yesJournal of Mathematics, 2021
We introduce the concepts of Cohen positive strongly p-summing and positive p-dominated m-homogeneous polynomials. The version of Pietsch’s domination theorem for the first class among other results and a Bu-type theorem is proved, as well as some ...

Metric Dimension Threshold of Graphs

open access: yesJournal of Mathematics, 2022
Let G be a connected graph. A subset S of vertices of G is said to be a resolving set of G, if for any two vertices u and v of G there is at least a member w of S such that du,w≠dv,w.

Radio Labelings of Lexicographic Product of Some Graphs

open access: yesJournal of Mathematics, 2021
Labeling of graphs has defined many variations in the literature, e.g., graceful, harmonious, and radio labeling. Secrecy of data in data sciences and in information technology is very necessary as well as the accuracy of data transmission and different ...
