Multiple solutions for a class of Schrödinger–Bopp–Podolsky system with sublinear nonlinearity

Electronic Journal of Qualitative Theory of Differential Equations
In this paper, we investigate the existence and concentration of solutions for the following Schrödinger–Bopp–Podolsky system with sublinear nonlinearity: \begin{equation*} \begin{cases} -\Delta u +\lambda V(x) u+ G(x)\phi u =f(x,u) & \text{in}~\mathbb ...

Numerical construction of structured matrices with given eigenvalues

Special Matrices, 2019
We consider a structured inverse eigenvalue problem in which the eigenvalues of a real symmetric matrix are specified and selected entries may be constrained to take specific numerical values or to be nonzero.

The Paradox of Mysticism in the Zhuangzi: Oneness, Multiplicity, and the Transformation of Self and Reality

Religions
This paper examines the four-stage process of mystical experience in the Huzi and Lady Yu allegories of the Zhuangzi. It begins with a lifeless stage enabled by the mystic’s purgation of the world and the self. It is followed by a revitalization stage in

Existence and multiplicity of positive radial solutions to nonlocal boundary-value problems in exterior domains

Electronic Journal of Differential Equations, 2016
In this article, we consider nonlocal p-Laplacian boundary-value problems with integral boundary conditions and a non-negative real-valued boundary condition as a parameter.
