The maximum principle with lack of monotonicity [PDF]

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.

On the maximum principle for viscosity solutions of fully nonlinear elliptic equations in general domain [PDF]

open access: yesLe Matematiche, 2007
We analyze the validity of the Maximum Principle for viscosity solutions of fully nonlinear second order elliptic equations in general unbounded domains under suitable structure conditions on the equation allowing notably quadratic growth in the gradient

The Maximum Entropy Production Principle: Its Theoretical Foundations and Applications to the Earth System [PDF]

open access: yes, 2010
The Maximum Entropy Production (MEP) principle has been remarkably successful in producing accurate predictions for non-equilibrium states. We argue that this is because the MEP principle is an effective inference procedure that produces the best ...

The geometry of the solution set of nonlinear optimal control problems [PDF]

open access: yes, 2005
In an optimal control problem one seeks a time-varying input to a dynamical systems in order to stabilize a given target trajectory, such that a particular cost function is minimized.

Sufficient Stochastic Maximum Principle in a Regime-Switching Diffusion Model [PDF]

open access: yes, 2011
We prove a sufficient stochastic maximum principle for the optimal control of a regime-switching diffusion model. We show the connection to dynamic programming and we apply the result to a quadratic loss minimization problem, which can be used to solve a

A Variational Framework for Nonlinear Chemical Thermodynamics Employing the Maximum Energy Dissipation Principle. [PDF]

open access: yes, 2009
Maximum energy dissipation principle is employed to nonlinear chemical thermodynamics in terms of distance variable (general displacement) from the global equilibrium, applyong the optimal control interpretation to develop a variational formulation.

Lagrangian submanifolds generated by the Maximum Entropy Principle [PDF]

open access: yes, 2004
We show that the Maximum Entropy principle (E.T. Jaynes, [8]) has a natural description in terms of Morse Families of a Lagrangian submanifold. This geometric approach becomes useful when dealing with the M.E.P. with nonlinear constraints.

A sufficient condition for null controllability of nonlinear control systems [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2009
Classical control methods such as Pontryagin Maximum Principle and Bang-Bang Principle and other methods are not usually useful for solving opti-mal control systems (OCS) specially optimal control of nonlinear systems (OCNS).

A Note on the Strong Maximum Principle for Fully Nonlinear Equations on Riemannian Manifolds [PDF]

open access: yesThe Journal of Geometric Analysis, 2021
Abstract We investigate strong maximum (and minimum) principles for fully nonlinear second-order equations on Riemannian manifolds that are non-totally degenerate and satisfy appropriate scaling conditions. Our results apply to a large class of nonlinear operators, among which Pucci’s extremal operators, some ...
