Controlled viscosity solutions of fully nonlinear rough PDEs [PDF]

open access: yes, 2014
We propose a definition of viscosity solutions to fully nonlinear PDEs driven by a rough path via appropriate notions of test functions and rough jets. These objects will be defined as controlled processes with respect to the driving rough path. We show that this notion is compatible with the seminal results of Lions and Souganidis and with the recent ...

Viscosity Solutions of Path-Dependent PDEs with Randomized Time [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2020
We introduce a new definition of viscosity solution to path-dependent partial differential equations, which is a slight modification of the definition introduced in [8]. With the new definition, we prove the two important results till now missing in the literature, namely, a general stability result and a comparison result for semicontinuous sub-/super-

Decay estimate of viscosity solutions of nonlinear parabolic PDEs and applications [PDF]

open access: yesLe Matematiche, 2013
The aim of this paper is to establish a decay estimate for viscosity solutions of nonlinear PDEs. As an application we prove existence and uniqueness for time almost periodic viscosity solutions.

Comparison of viscosity solutions for a class of second-order PDEs on the Wasserstein space

open access: yesCommunications in Partial Differential Equations
We prove a comparison result for viscosity solutions of second order parabolic partial differential equations in the Wasserstein space. The comparison is valid for semisolutions that are Lipschitz continuous in the measure in a Fourier-Wasserstein metric and uniformly continuous in time.

Conductivity and energy change in Carreau nanofluid flow along with magnetic dipole and Darcy-Forchheimer relation

open access: yesAlexandria Engineering Journal, 2021
The current research article explores the bio-convection magnetized Carreau-nanofluid flow utilizing activation energy and magnetic dipole. Magnetic nanomaterials have significant effect on the magnetized behavior of ferrofluids which leads to robust the

Fully nonlinear stochastic and rough PDEs: Classical and viscosity solutions [PDF]

open access: yesProbability, Uncertainty and Quantitative Risk, 2020
Abstract We study fully nonlinear second-order (forward) stochastic PDEs. They can also be viewed as forward path-dependent PDEs and will be treated as rough PDEs under a unified framework. For the most general fully nonlinear case, we develop a local theory of classical solutions and then define viscosity solutions through smooth test ...
