The maximum principles and symmetry results for viscosity solutions of fully nonlinear equations

Journal of Differential Equations, 2015
This paper is concerned about maximum principles and radial symmetry for viscosity solutions of fully nonlinear partial differential equations. We obtain the radial symmetry and monotonicity properties for nonnegative viscosity solutions of begin{equation}F (D^2 u)+u^p=0 \quad \quad \mbox{in}\ \mathbb R^n \label{abs}\end{equation} under the asymptotic ...

The abstract maximum principle and its application in the differential games theory

Научно-технический вестник информационных технологий, механики и оптики
The problem of optimal control involving two opposing players is considered where optimality is understood in the minimax sense of achieving the best guaranteed outcome, and the control strategy is constructed with respect to the worst case admissible ...

Positive solutions for parametric nonlinear periodic problems with competing nonlinearities

Electronic Journal of Differential Equations, 2015
We consider a nonlinear periodic problem driven by a nonhomogeneous differential operator plus an indefinite potential and a reaction having the competing effects of concave and convex terms.

Path‐Decoupled Cation‐Eutaxy III–V van der Waals Memristive Semiconductors for Mitigating the Neuromorphic Accuracy‐Energy Trade‐off

Advanced Materials, EarlyView.
Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...

A Maximum Principle for Bounded Solutions of the Telegraph Equations and Applications to Nonlinear Forcings

Journal of Mathematical Analysis and Applications, 2000
The authors prove a weak maximum principle for the solutions of the telegraph equation \[ u_{tt}- u_{xx}+ cu_t+\lambda u= f(t,x)\qquad (c>0) \] which are \(2\pi\)-periodic with respect to \(x\) and bounded over \(\mathbb{R}\) with respect to \(t\). Then the maximum principle is generalized to the case where \(f\) is replaced by an element in a suitable

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

Advanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.
