چکیده
We establish the existence and uniqueness of strong solutions to stochastic porous media equations driven by Lévy noise on a $$\sigma $$ -finite measure space $$(E,{\mathcal {B}}(E),\mu )$$ , with Laplacian replaced negative definite self-adjoint operator. The coefficient $$\Psi is only assumed satisfy increasing Lipschitz nonlinearity assumption, without restriction $$r\Psi (r)\rightarrow \infty as $$r\rightarrow for $$L^2(\mu -initial data. also extend state space, which avoids transience assumption L or boundedness $$L^{-1}$$ in $$L^{r+1}(E,{\mathcal some $$r\ge 1$$ . Examples operators include fractional powers Laplacian, i.e., $$L=-(-\Delta )^\alpha ,\ \alpha \in (0,1]$$ generalized $$\mathrm Schr\ddot{o}dinger$$ operators, $$L=\Delta +2\frac{\nabla \rho }{\rho }\cdot \nabla Laplacians fractals.

Non-Monotone Stochastic Generalized Porous Media Equations∗
By using the Nash inequality and a monotonicity approximation argument, existence and uniqueness of strong solutions are proved for a class of non-monotone stochastic generalized porous media equations. Moreover, we prove for a large class of stochastic PDE that the solutions stay in the smaller L2-space provided the initial value does, so that some recent results in the literature are consider...
متن کاملNonlinear 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...
متن کاملConcentration of Invariant Measures for Stochastic Generalized Porous Media Equations
By using Bernstein functions, existence and concentration properties are studied for invariant measures of the infinitesimal generators associated to a large class of stochastic generalized porous media equations. In particular, results derived in [4] are extended to equations with non-constant and stronger noises. Analogous results are also proved for invariant probability measures for strong ...

متن کاملStochastic Partial Differential Equations Driven by Lévy Space - Time White Noise
In this paper we develop a white noise framework for the study of stochastic partial differential equations driven by a d-parameter (pure jump) Lévy white noise. As an example we use this theory to solve the stochastic Poisson equation with respect to Lévy white noise for any dimension d. The solution is a stochastic distribution process given explicitly. We also show that if d ≤ 3, then this s...
