On the parabolic model for the harmonic oscillator II: global existence and invariant measures

Aurélien Deya, Reika Fukuizumi, Laurent Thomann

We establish an a priori bound for the dynamical parabolic model with harmonic potential. This bound yields the global well-posedness of the equation and, via the Krylov-Bo…

An Effective SPDE Model for a Schrödinger Equation with a Fluctuating Magnetic Potential

Franco Flandoli, Reika Fukuizumi, Francesco Grotto +1

We consider the Schrödinger equation for a charged particle in a randomly fluctuating external magnetic field and establish a singular perturbation limit in which the solution conv…

Ergodicity for a Constantin-Lax-Majda-DeGregorio model of turbulent flow

Shunsuke Fujita, Reika Fukuizumi, Takashi Sakajo

This paper presents a mathematical analysis of a one-dimensional model of turbulence based on a stochastic generalized Constantin-Lax-Majda-DeGregorio (gCLMG) equation. We focus on…

On the parabolic model for the harmonic oscillator: diagrams and local existence

Aurélien Deya, Reika Fukuizumi, Laurent Thomann

We prove the local wellposedness of the (renormalized) parabolic model associated with the harmonic oscillator on , that is, the equation formally written as…

The stochastic fast logarithmic equation in with multiplicative Stratonovich noise

Ioana Ciotir, Reika Fukuizumi, Dan Goreac

This paper is concerned with the existence and uniqueness of the solution for the stochastic fast logarithmic equation with Stratonovich multiplicative noise in fo…
