Expander Graphs in Pure and Applied Mathematics [PDF]

open access: greenarXiv, 2011
Expander graphs are highly connected sparse finite graphs. They play an important role in computer science as basic building blocks for network constructions, error correcting codes, algorithms and more. In recent years they have started to play an increasing role also in pure mathematics: number theory, group theory, geometry and more. This expository

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

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.
