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 the fractional magnetic Schrödinger equations with critical growth

Journal of Mathematics and Physics, 2021
In this paper, we study the following critical fractional Schrodinger equations with the magnetic field: e2s(−Δ)A/esu+V(x)u=λf(|u|)u+|u|2s*−2uinRN, where ɛ and λ are positive parameters and V:RN→R and A:RN→RN are continuous electric and magnetic ...
