Euclidean-Lorentzian Dichotomy and Algebraic Causality in Finite Ring Continuum [PDF]
We present a concise and self-contained extension of the Finite Ring Continuum (FRC) program, showing that symmetry-complete prime shells Fp with p=4t+1 exhibit a fundamental Euclidean-Lorentzian dichotomy.

Interval Ranges of Fuzzy Sets Induced by Arithmetic Operations Using Gradual Numbers
Wu introduced the interval range of fuzzy sets. Based on this, he defined a kind of arithmetic of fuzzy sets using a gradual number and gradual sets. From the point of view of soft computing, this definition provides a new way of handling the arithmetic ...

Granular computational homogenisation of composite structures with imprecise parameters
The paper presents the formulation of a granular computational homogenisation problem and the proposition of a method to solve it, which enables multiscale analysis of materials with uncertain microstructure parameters.

A Rigorous Extension of the Schönhage-Strassen Integer Multiplication Algorithm Using Complex Interval Arithmetic [PDF]
Multiplication of n-digit integers by long multiplication requires O(n^2) operations and can be time-consuming. In 1970 A. Schoenhage and V. Strassen published an algorithm capable of performing the task with only O(n log(n)) arithmetic operations over ...

Tiling by translates of a function: results and open problems
Tiling by translates of a function: results and open problems, Discrete Analysis 2021:12, 24 pp. Let $f$ be a function from $\mathbb R$ to $\mathbb R$, and for each $\lambda\in\mathbb R$, let $T_\lambda$ be the translate of $f$ by $\lambda$, that is ...

Multiple recurrence and large intersections for abelian group actions
Multiple recurrence and large intersections for abelian group actions, Discrete Analysis 2021:18, 91 pp. In 1975, Szemerédi proved his famous theorem that asserts that for every positive integer $k$ and every $\delta>0$ there exists $n$ such that every ...

Approximate Euclidean Ramsey theorems
According to a classical result of Szemerédi, every dense subset of 1,2,…,N contains an arbitrary long arithmetic progression, if N is large enough. Its analogue in higher dimensions due to Fürstenberg and Katznelson says that every dense subset of {1,2,…
