Sharp Contradiction for Local-Hidden-State Model in Quantum Steering [PDF]
, 2016 In quantum theory, no-go theorems are important as they rule out the existence of a particular physical model under consideration. For instance, the Greenberger-Horne-Zeilinger (GHZ) theorem serves as a no-go theorem for the nonexistence of local hidden ...

On the nonexistence of degenerate phase-shift discrete solitons in a dNLS nonlocal lattice [PDF]
, 2018 We consider a one-dimensional discrete nonlinear Schr{\"o}dinger (dNLS) model featuring interactions beyond nearest neighbors. We are interested in the existence (or nonexistence) of phase-shift discrete solitons, which correspond to four-sites vortex ...

Generalized Picone inequalities and their applications to (p,q)-Laplace equations
Open Mathematics, 2020 We obtain a generalization of the Picone inequality which, in combination with the classical Picone inequality, appears to be useful for problems with the (p,q)(p,q)-Laplace-type operators.

Nonlinear Schr\"odinger equation in the Bopp-Podolsky electrodynamics: solutions in the electrostatic case [PDF]
, 2018 We study the following nonlinear Schr\"odinger-Bopp-Podolsky system \[ \begin{cases} -\Delta u + \omega u + q^{2}\phi u = |u|^{p-2}u -\Delta \phi + a^2 \Delta^2 \phi = 4\pi u^2 \end{cases} \hbox{ in }\mathbb{R}^3 \] with $a,\omega>0$.

The Brezis–Nirenberg problem for nonlocal systems
Advances in Nonlinear Analysis, 2016 By means of variational methods we investigate existence, nonexistence as well as regularity of weak solutions for a system of nonlocal equations involving the fractional laplacian operator and with nonlinearity reaching the critical growth and ...

Electronic Journal of Qualitative Theory of Differential Equations, 2016 We study non-monotone positive solutions of the second-order linear differential equations: $(p(t)x')' + q(t) x = e(t)$, with positive $p(t)$ and $q(t)$. For the first time, some criteria as well as the existence and nonexistence of non-monotone positive

Rotationally symmetric harmonic diffeomorphisms between surfaces [PDF]
, 2013 In this paper, we show that the nonexistence of rotationally symmetric harmonic diffeomorphism between the unit disk without the origin and a punctured disc with hyperbolic metric on the target.Comment: Minor typos ...

Novel Beings and Assisted Nonexistence [PDF]
Cambridge Quarterly of Healthcare Ethics, 2021 AbstractThis article engages with the legal regulation of end-of-existence decisionmaking for novel beings, specifically assisted nonexistence for such entities. The author explains the concept of a legal model for assisted death by reference to the substantive features of legal regimes in three jurisdictions in which assisted suicide or euthanasia is ...

On nonexistence of Baras--Goldstein type for higher-order parabolic equations with singular potentials [PDF]
, 2009 An analogy of nonexistence result by Baras and Goldstein (1984), for the heat equation with inverse singular potential, is proved for 2mth-order linear parabolic equations with Hardy-supercritical singular potentials.
