On the Diversity and Multiplicity of Theories in Mathematics Education

open access: closed, 2014
The paper starts with a brief history of theories that guided mathematics education research presented in PME meetings and publications. There seems to be a “feeling” that mathematics education should rely on theoretical grounds to become a legitimate field of research. Yet, the current situation with multiplicity of theories is troubling.

On supercritical elliptic problems: existence, multiplicity of positive and symmetry breaking solutions

Mathematische Annalen, 2022
The main thrust of our current work is to exploit very specific characteristics of a given problem in order to acquire improved compactness for supercritical problems and to prove existence of new types of solutions.

Multiple representations and mathematical creativity

Thinking Skills and Creativity, 2021
Abstract The primary purpose of this study is to reveal how multiple representations and/or visualizations can be used as an intervention to promote students’ mathematical creativity. The second purpose is to observe how multiple representations and/or visualizations can be used as a psychometric tool to measure students’ creative thinking abilities ...

Existence and Multiplicity Results for Kirchhoff-Type Problems on a Double-Phase Setting

Mediterranean Journal of Mathematics, 2020
In this paper, we study two classes of Kirchhoff-type problems set on a double-phase framework. That is, the functional space where finding solutions coincides with the Musielak–Orlicz–Sobolev space W01,H(Ω)\documentclass[12pt]{minimal} \usepackage ...

Multiplicity results for double phase problems in RN

Journal of Mathematics and Physics, 2020
We consider a double phase problem in RN with a q−1-superlinear subcritical Caratheodory reaction term, which does not satisfy the Ambrosetti–Rabinowitz condition.

Reverse Mathematics and Ordinal Multiplication

Mathematical Logic Quarterly, 1998
AbstractThis paper uses the framework of reverse mathematics to analyze the proof theoretic content of several statements concerning multiplication of countable well‐orderings. In particular, a division algorithm for ordinal arithmetic is shown to be equivalent to the subsystem ATR0.
