Investigating the affordances of a flipped mathematics classroom from an activity theoretical perspective
(Peer reviewed; Journal article, 2020)Flipped Classroom as a pedagogical framework has gained popularity at secondary and tertiary levels of mathematics education, but there is a lack of research based on a solid theoretical foundation. This article considers ... -
Isometric factorization of vector measures and applications to spaces of integrable functions
(Peer reviewed; Journal article, 2021)Let X be a Banach space, Σ be a σ-algebra, and be a (countably additive) vector measure. It is a well known consequence of the Davis-Figiel-Johnson-Pełczyński factorization procedure that there exist a reflexive Banach ... -
An Itô Formula for rough partial differential equations and some applications
(Peer reviewed; Journal article, 2020)We investigate existence, uniqueness and regularity for solutions of rough parabolic equations of the form ∂tu−Atu−f = (X˙t(x)·∇+Y˙ t(x))u on [0, T ]×Rd . To do so, we introduce a concept of “differential rough driver”, ... -
Job satisfaction of mathematics teachers: an empirical investigation to quantify the contributions of teacher self‑efficacy and teacher motivation to teach
(Peer reviewed; Journal article, 2023)The shortage of mathematics teachers necessitates deliberate efforts to retain high-quality ones in many parts of the world. This puts teacher job satisfaction in the spotlight since satisfied teachers are likely to retain ... -
“The joy that engineers and mathematicians have come together.” Richard von Mises’ foundation of ZAMM, and its “Tasks and Goals” (1920/21)

The Limit Notion at Three Educational Levels in Three Countries
(Peer reviewed; Journal article, 2022)This paper documents how the limit concept is treated in high school, at a university and in teacher education in England, France and Sweden. To this end we make use of vignettes, data-grounded accounts of the situation ... -
A Multi Parameter Forecasting for Stock Time Series Data Using LSTM and Deep Learning Model
(Peer reviewed; Journal article, 2023)Financial data are a type of historical time series data that provide a large amount of information that is frequently employed in data analysis tasks. The question of how to forecast stock prices continues to be a topic ... -
New applications of extremely regular function spaces
(Peer reviewed; Journal article, 2019)Let L be an infinite locally compact Hausdorff topological space. We show that extremely regular subspaces of C0(L) have very strong diameter 2 properties and, for every real number ε with 0 <ε<1, contain an ε-isometric ... -
A Non-normal-Mode Marginal State of Convection in a Porous Rectangle
(Journal article; Peer reviewed, 2019)The fourth-order Darcy–Bénard eigenvalue problem for onset of thermal convection in a 2D rectangular porous box is investigated. The conventional type of solution has normal-mode dependency in at least one of the two spatial ... -
The object-tool duality in mathematical modelling - a framework to analyze students’ appropriation of Sankey diagrams to model dynamic processes
(Peer reviewed; Journal article, 2020)Students often do not experience the relevance of learning mathematics. This paper reports on an exploratory case study, in which a class of grade 8 students (n=35) was introduced to Sankey diagrams. The aim was to explore ... -
On Daugavet indices of thickness
(Peer reviewed; Journal article, 2021)Inspired by R. Whitley's thickness index the last named author recently introduced the Daugavet index of thickness of Banach spaces. We continue the investigation of the behavior of this index and also consider two new ... -

On the asymptotic behavior of solutions to a class of third-order nonlinear neutral differential equations
(Peer reviewed; Journal article, 2020)By using comparison principles, we analyze the asymptotic behavior of solutions to a class of third-order nonlinear neutral differential equations. Due to less restrictive assumptions on the coefficients of the equation ... -

Onset of Convection in an Inclined Anisotropic Porous Layer with Internal Heat Generation
(Peer reviewed; Journal article, 2019)The onset of convection in an inclined porous layer which is heated internally by a uniform distribution of heat sources is considered. We investigate the combined effects of inclination, anisotropy and internal heat ... -
Oscillation results for second-order nonlinear neutral differential equations
(Journal article; Peer reviewed, 2013)We obtain several oscillation criteria for a class of second-order nonlinear neutral differential equations. New theorems extend a number of related results reported in the literature and can be used in cases where known ... -
Perspectives and reflections on teaching linear algebra
(Peer reviewed; Journal article, 2020)This paper presents ‘expert opinions’ on what should be taught in a first-year linear algebra course at university; the aim is to gain a generic picture and general guiding principles for such a course. Drawing on a Delphi ...
