Path-by-path well-posedness of nonlinear diffusion equations with multiplicative noise

چکیده

We prove the path-by-path well-posedness of stochastic porous media and fast diffusion equations driven by linear, multiplicative noise. As a consequence, we obtain existence random dynamical system. This solves an open problem raised in [Barbu Röckner (2011) [4] ], (2018) [6] [Gess (2014) [11] ]. Nous prouvons le caractère bien posé, trajectoire-par-trajectoire, des équations milieux poreux et de rapide stochastiques, perturbées par un bruit linéaire multiplicatif. En conséquence, nous obtenons l'existence d'un système dynamique aléatoire. Cela résout problème soulevé dans

Well-posedness and asymptotic behavior for stochastic reaction-diffusion equations with multiplicative Poisson noise∗

We establish well-posedness in the mild sense for a class of stochastic semilinear evolution equations with a polynomially growing quasi-monotone nonlinearity and multiplicative Poisson noise. We also study existence and uniqueness of invariant measures for the associated semigroup in the Markovian case. A key role is played by a new maximal inequality for stochastic convolutions in Lp spaces .

Symmetric path integrals for stochastic equations with multiplicative noise

A Langevin equation with multiplicative noise is an equation schematically of the form dq/dt=-F(q)+e(q)xi, where e(q)xi is Gaussian white noise whose amplitude e(q) depends on q itself. I show how to convert such equations into path integrals. The definition of the path integral depends crucially on the convention used for discretizing time, and I specifically derive the correct path integral w...

Nonlinear stochastic equations with multiplicative Lévy noise.

The Langevin equation with a multiplicative Lévy white noise is solved. The noise amplitude and the drift coefficient have a power-law form. A validity of ordinary rules of the calculus for the Stratonovich interpretation is discussed. The solution has the algebraic asymptotic form and the variance may assume a finite value for the case of the Stratonovich interpretation. The problem of escapin...
