Viscosity Solution [PDF]

open access: yesComputer Vision, A Reference Guide, 2014
Viscosity solution is a notion of weak solution for a class of partial differential equations of Hamilton-Jacobi type. The range of applications of the notions of viscosity solution and Hamilton-Jacobi equations is enormous, including common class of partial differential equations such as evolutive problems and problems with boundary conditions ...

Characterizations of the viscosity solution of a nonlocal and nonlinear equation induced by the fractional p-Laplace and the fractional p-convexity

Advances in Calculus of Variations, 2023
In this paper, when studying the connection between the fractional convexity and the fractional p-Laplace operator, we deduce a nonlocal and nonlinear equation.

A class of infinite-horizon stochastic delay optimal control problems and a viscosity solution to the associated HJB equation

, 2018
In this paper, we investigate a class of infinite-horizon optimal control problems for stochastic differential equations with delays for which the associated second order Hamilton−Jacobi−Bellman (HJB) equation is a nonlinear partial differential equation

Solution viscosity regulates chondrocyte proliferation and phenotype during 3D culture.

Journal of materials chemistry. B, 2019
Cells are surrounded by an extracellular matrix (ECM), which controls cellular functions through biological or physicochemical cues. In particular, cartilage tissues have abundant ECM that is viscoelastic and provides the necessary signals for the ...

The negative of regular cosmological time function is a viscosity solution

, 2014
In this paper we show that for a spacetime (M, g) with regular cosmological time function τ, −τ is a viscosity solution to the Hamilton-Jacobi equation g(∇u, ∇u) = −1 and shares some analogous properties with the so-called weak KAM solutions.

Effect of Solutes on the Viscosity of Supercritical Solutions

The Journal of Physical Chemistry B, 2007
This study shows that solutes can impart significant structure to supercritical solutions, resulting in unexpectedly high solution viscosity at pressures close to the critical value. The viscosity passes through a minimum as the pressure is increased, and this is accounted for by a solvation of the solutes leading to a decrease in solute-solute ...

The viscosity of short polyelectrolyte solutions

Soft Matter, 2014
We consider the viscosity of solutions of highly charged short polyelectrolytes. Our system is a poly(styrene-maleic acid) copolymer solution (SMA) with various added salt concentrations in dilute and semidilute regimes. The SMA solutions show some particular features: (i) variations of the specific viscosity measured for different values of ...
