On short wave-long wave interactions\\ in the relativistic context: Application to the Relativistic Euler Equations

João Paulo Dias, Hermano Frid

In this paper we introduce a model of relativistic short wave-long wave interaction where the short waves are described by the massless -dimensional Thirring model of nonlinea…

A Boundary Value Problem for a Class of Anisotropic Stochastic Degenerate Parabolic-Hyperbolic Equations

Hermano Frid, Yachun Li, Daniel Marroquin +2

We establish the well-posedness of an initial-boundary value problem of mixed type for a stochastic nonlinear parabolic-hyperbolic equation on a space domain $\cO=\cO'\X\cO''$ wher…

On short wave-long wave interactions in the relativistic context

João Paulo Dias, Hermano Frid

In this paper we introduce models of short wave-long wave interactions in the relativistic setting. In this context the nonlinear Schrödinger equation is no longer adequate for des…

On Hodge decomposition, effective viscous flux and compressible Navier-Stokes

Hermano Frid, Daniel Marroquin, João F. C. Nariyoshi

It has been known, since the pioneering works by Serre, Hoff, Vaĭgant-Kazhikhov, Lions and Feireisl, among others, the regularizing properties of the effective viscous flux and its…

Homogenization of Stochastic Conservation Laws with Multiplicative Noise

Hermano Frid, Kenneth H. Karlsen, Daniel Marroquin

We consider the generalized almost periodic homogenization problem for two different types of stochastic conservation laws with oscillatory coefficients and multiplicative noise. I…

The Strong Trace Property and the Neumann Problem for Stochastic Conservation Laws

Hermano Frid, Yachun Li, Daniel Marroquin +2

We establish the well-posedness of the Neumann problem for stochastic conservation laws with multiplicative noise. As a major step for establishing the uniqueness of the kinetic so…

Global smooth solutions with large data for a system modeling aurora type phenomena in the 2-torus

Hermano Frid, Daniel R. Marroquin, João F. C. Nariyoshi

We prove existence and uniqueness of smooth solutions with large initial data for a system of equations modeling the interaction of short waves, governed by a nonlinear Schrödinger…

Modeling Aurora Type Phenomena by Short Wave-Long Wave Interactions in Multi-Dimensional Large MHD Flows

Hermano Frid, Daniel R. Marroquin, Ronghua Pan

We establish the convergence of an approximation scheme to a model for aurora type phenomena. The latter, mathematically, means a system describing the short wave-long wave (SW-LW)…

A note on the stochastic weakly* almost periodic homogenization of fully nonlinear elliptic equations

Hermano Frid

A function $f\in \BUC(\R^d)$ is said to be weakly* almost periodic, denoted $f\in\APs(\R^d)$, if there is $g\in\AP(\R^d)$, such that, $\oM(|f-g|)=0$, where $\BUC(\R^d)$ and $\AP(\R…
