Aspect perception and rule‐following in Wittgenstein's Philosophical Investigations

Philosophical Investigations, EarlyView.
Abstract This paper aims to highlight a distinctive, projective, mode of aspect perception within Wittgenstein's philosophy that has gone underappreciated in the scholarly literature. Although it bears a family resemblance to other instances of the phenomenon Wittgenstein describes as ‘noticing an aspect’ in PI Part II §113, it is distinctive in that ...

3D Graphics with Spreadsheets

Spreadsheets in Education, 2009
In the article, the formulas for orthographic parallel projection of 3D bodies on computer screen are derived using secondary school vector algebra. The spreadsheet implementation is demonstrated in six applications that project bodies with increasing ...

Radical cube zero selfinjective algebras of finite complexity

Journal of Pure and Applied Algebra, 2011
Abstract One of our main results is a classification of all the possible quivers of selfinjective radical cube zero finite-dimensional algebras over an algebraically closed field having finite complexity. In the paper (Erdmann and Solberg, 2011)  [5] we classified all weakly symmetric algebras with support varieties via Hochschild cohomology ...

Where Mathematical Symbols Come From

Topics in Cognitive Science, EarlyView.
Abstract There is a sense in which the symbols used in mathematical expressions and formulas are arbitrary. After all, arithmetic would be no different if we would replace the symbols ‘+$+$’ or ‘8’ by different symbols. Nevertheless, the shape of many mathematical symbols is in fact well motivated in practice.

On the Fourier transform of measures in Besov spaces

Bulletin of the London Mathematical Society, EarlyView.
Abstract We prove quantitative estimates for the decay of the Fourier transform of the Riesz potential of measures that are in homogeneous Besov spaces of the negative exponent: ∥Iαμ̂∥Lp,∞⩽C∥μ∥Mb12supt>0td−β2∥pt*μ∥∞12,$$\begin{align*} \Vert \widehat{I_{\alpha }\mu }\Vert _{L^{p, \infty }} \leqslant C \Vert \mu \Vert _{M_b}^{\frac{1}{2}}{\left(\sup _{t ...

Quasi‐invariance of Gaussian measures for the 3d$3d$ energy critical nonlinear Schrödinger equation

Communications on Pure and Applied Mathematics, Volume 78, Issue 12, Page 2305-2353, December 2025.
Abstract We consider the 3d$3d$ energy critical nonlinear Schrödinger equation with data distributed according to the Gaussian measure with covariance operator (1−Δ)−s$(1-\Delta)^{-s}$, where Δ$\Delta$ is the Laplace operator and s$s$ is sufficiently large. We prove that the flow sends full measure sets to full measure sets. We also discuss some simple

The matricial relaxation of a linear matrix inequality

, 2011
Given linear matrix inequalities (LMIs) L_1 and L_2, it is natural to ask: (Q1) when does one dominate the other, that is, does L_1(X) PsD imply L_2(X) PsD? (Q2) when do they have the same solution set? Such questions can be NP-hard. This paper describes

Hyperspectral Imaging: The Intelligent Eye to Uncover the Password of Plant Science

Modern Agriculture, Volume 3, Issue 2, December 2025.
Hyperspectral imaging (HSI) has emerged as a powerful non‐destructive technique for characterisation of the plant phenotype and physiological traits. The ongoing development of cost‐effective hardware, coupled with standardised acquisition protocols and open‐access spectral libraries, is accelerating its integration with multi‐omics approaches to ...

The Impact of a Digital Game on Spatial Reasoning for Elementary School Students

Journal of Computer Assisted Learning, Volume 41, Issue 6, December 2025.
ABSTRACT Background Spatial reasoning is a crucial factor in students' mathematics performance. Providing training to elementary students in spatial reasoning is a promising way to improve their performance in mathematics. The use of digital games to assist instruction has been found to have a positive impact on students' spatial reasoning.
