چکیده
We deal with the Sobolev space theory for stochastic partial differential equation (SPDE) driven by Wiener processes $$\begin{aligned} \partial _{t}^{\alpha }u=\left( \phi (\varDelta ) u +f(u) \right) + _t^\beta \sum _{k=1}^\infty \int _0^t g^k(u)\,dw_s^k, \quad t>0, \,x\in {\mathbb {R}}^d \end{aligned}$$ as well SPDE space-time white noise ^{\alpha }_{t}u=\phi )u f(u) ^{\beta -1}_{t}h(u) {\dot{W}}, t>0,\, x\in {R}}^d. Here, $$\alpha \in (0,1), \beta < \alpha +1/2$$ , $$\{w_t^k : k=1,2,\ldots \}$$ is a family of independent one-dimensional and $${\dot{W}}$$ defined on $$[0,\infty )\times {R}}^d$$ . The time non-local operator $$\partial }$$ denotes Caputo fractional derivative order $$ function $$\phi Bernstein function, spatial )$$ integro-differential whose symbol $$-\phi (|\xi |^2)$$ In other words, infinitesimal generator d-dimensional subordinate Brownian motion. prove uniqueness existence results in spaces obtain maximal regularity solutions.

The new implicit finite difference scheme for two-sided space-time fractional partial differential equation
Fractional order partial differential equations are generalizations of classical partial differential equations. Increasingly, these models are used in applications such as fluid flow, finance and others. In this paper we examine some practical numerical methods to solve a class of initial- boundary value fractional partial differential equations with variable coefficients on a finite domain. S...
متن کاملSolving nonlinear space-time fractional differential equations via ansatz method
In this paper, the fractional partial differential equations are defined by modified Riemann-Liouville fractional derivative. With the help of fractional derivative and fractional complex transform, these equations can be converted into the nonlinear ordinary differential equations. By using solitay wave ansatz method, we find exact analytical solutions of the space-time fractional Zakharov Kuz...
متن کاملThe Fundamental Solutions of the Space, Space-Time Riesz Fractional Partial Differential Equations with Periodic Conditions
In this paper, the space-time Riesz fractional partial differential equations with periodic conditions are considered. The equations are obtained from the integral partial differential equation by replacing the time derivative with a Caputo fractional derivative and the space derivative with Riesz potential. The fundamental solutions of the space Riesz fractional partial differential equation (...
متن کاملHilbert Space Methods for Partial Differential Equations
i Preface This book is an outgrowth of a course which we have given almost periodically over the last eight years. It is addressed to beginning graduate students of mathematics, engineering, and the physical sciences. Thus, we have attempted to present it while presupposing a minimal background: the reader is assumed to have some prior acquaintance with the concepts of " linear " and " continuo...
متن کاملImplicit Space-Time Domain Decomposition Methods for Stochastic Parabolic Partial Differential Equations
We introduce and study parallel space-time domain decomposition methods for solving deterministic and stochastic parabolic equations. Traditional parallel algorithms solve parabolic problems time step by time step. The parallelism is restricted to each time step, and the algorithms are purely sequential in time. In this paper, we develop some overlapping Schwarz methods whose subdomains cover b...
