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.

Multiplicity and limit of solutions for logarithmic Schrödinger equations on graphs

Journal of Mathematics and Physics
Let Ω be a finite connected subset of a locally finite graph G = (V, E) with the vertex set V and the edge set E. We investigate the logarithmic Schrödinger equation on Ω with the nonlinear term |u|p−2u log u2. For p > 2, through two different approaches

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.

Existence and multiplicity of triple weak solutions for a nonlinear elliptic problem with fourth-order operator and Hardy potential

AIMS Mathematics
This study investigates the existence of triple weak solutions for a system of nonlinear elliptic equations with a fourth-order operator. The problem arises in the mathematical modeling of complex physical phenomena.

Demyelination patterns in a mathematical model of multiple sclerosis

Journal of Mathematical Biology, 2016
In this paper we derive a reaction-diffusion-chemotaxis model for the dynamics of multiple sclerosis. We focus on the early inflammatory phase of the disease characterized by activated local microglia, with the recruitment of a systemically activated immune response, and by oligodendrocyte apoptosis. The model consists of three equations describing the

Multiplicity and Concentration Results for a Magnetic Schrödinger Equation With Exponential Critical Growth in ℝ2

International mathematics research notices, 2019
In this paper we study the following nonlinear Schrödinger equation with magnetic field $$\begin{align*} \left(\frac{\varepsilon}{i}\nabla-A(x)\right)^{2}u+V(x)u=f(| u|^{2})u,\quad x\in\mathbb{R}^{2}, \end{align*}$$where $\varepsilon>0$ is a parameter,
