A principle of maximum ignorance for semiclassical gravity [PDF]

open access: yesJournal of High Energy Physics, 2023
The principle of maximum ignorance posits that the coarse-grained description of a system is maximally agnostic about its underlying microscopic structure.

Improving the Minimum Free Energy Principle to the Maximum Information Efficiency Principle [PDF]

open access: yesEntropy
Friston proposed the Minimum Free Energy Principle (FEP) based on the Variational Bayesian (VB) method. This principle emphasizes that the brain and behavior coordinate with the environment, promoting self-organization. However, it has a theoretical flaw,

The maximum principle with lack of monotonicity

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
We establish a maximum principle for the weighted $(p,q)$-Laplacian, which extends the general Pucci–Serrin strong maximum principle to this quasilinear abstract setting.

Principal eigenvalues for k-Hessian operators by maximum principle methods

open access: diamondMathematics in Engineering, 2021
For fully nonlinear $k$-Hessian operators on bounded strictly $(k-1)$-convex domains $\Omega$ of $\R^N$, a characterization of the principal eigenvalue associated to a $k$-convex and negative principal eigenfunction will be given as the supremum over ...

The strong maximum principle for Schrödinger operators on fractals

open access: greenDemonstratio Mathematica, 2019
We prove a strong maximum principle for Schrödinger operators defined on a class of postcritically finite fractal sets and their blowups without boundary.

Introduction to the Pontryagin Maximum Principle for Quantum Optimal Control [PDF]

open access: yesPRX Quantum, 2020
Optimal Control Theory is a powerful mathematical tool, which has known a rapid development since the 1950s, mainly for engineering applications. More recently, it has become a widely used method to improve process performance in quantum technologies by ...

On energy stable, maximum-principle preserving, second order BDF scheme with variable steps for the Allen-Cahn equation [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2020
In this work, we investigate the two-step backward differentiation formula (BDF2) with nonuniform grids for the Allen-Cahn equation. We show that the nonuniform BDF2 scheme is energy stable under the time-step ratio restriction $r_k:=\tau_k/\tau_{k-1}

Arbitrarily high-order exponential cut-off methods for preserving maximum principle of parabolic equations [PDF]

open access: yesSIAM Journal on Scientific Computing, 2020
A new class of high-order maximum principle preserving numerical methods is proposed for solving parabolic equations, with application to the semilinear Allen--Cahn equation.

Polyconvex functionals and maximum principle

open access: yesMathematics in Engineering, 2023
Let us consider continuous minimizers $ u : \bar \Omega \subset \mathbb{R}^n \to \mathbb{R}^n $ of $ \mathcal{F}(v) = \int_{\Omega} [|Dv|^p \, + \, |{\rm det}\,Dv|^r] dx, $ with $ p > 1 $ and $ r > 0 $; then it is known that every ...
