A method has been developed for finding the characteristic function φ( u , t ) = E exp i u ′ X ( t ) of the solution X ( t ) of a non-linear stochastic differential equation driven by Poisson white noise. Poisson white noise can be viewed as a sequence of independent identically...
What is the difference between a Partial Differential Equation and an Ordinary Differential Equation? Examples of Differential Equations Differential equations have multiple applications in math, physics, and science, in general. They contain unknown functions, their derivativ...

A specific partial differential equation in a bounded domain is studied. It is stated that without any boundary condition the equation admits either a finite number of solutions or has no solution in general.doi:10.1080/17476930701470137Z. D. Usmanov...
Numerical study of a partial differential equation 来自 Semantic Scholar 喜欢 0 阅读量: 14 作者: SKD Magazieva 摘要: Possible stable equilibrium positions of a set of ordinary differential equations, obtained by the method of straight lines from a non-linear evolutionary partial differential ...
第14 段提到 Navier–Stokes 方程,它是描述粘性流体物质(viscous fluid substances) 的运动的一组偏微分方程 (partial differential equations)。NS 方程形式很多,例如不可压缩的 (incompressible) Navier–Stokes 方程 \dfrac{\partial \boldsymbol{u}}{\partial t} + (\boldsymbol{u} \cdot \nabla)\boldsymbol...
Partial differential equations are a branch of differential equations in which the function is comprised of two or more independent variables. For example, the heat conduction equation is a partial differential equation: α2δ2u(x,t)δx2=δu(x,t)δt....
Fig. 2(b), where the agents are parametrized by a random index i); is it possible to find a collective description of the dynamics in these time series based on a data-driven, emergent spatial variable, and in the form of a partial differential equation, involving partial derivatives in ...
To take into account the effects of Magneto-Gas-Dynamics (MGD) for unsteady, viscous, chemically reacting multi-species flows, a partial differential equation for the magnetic induction vector derived from the set of Maxwell equations has to be considered coupled with fully compressible Navier–Stokes...
