阶order 此外,微分方程的阶(order)定义为方程中出现的最高阶导数的阶数,比如(1.1)是一阶ODE,(1.2)是二阶ODE,(1.3)是二阶PDE 线性与非线性ODE linear vs. nonlinear 一个简单的判断方法是,对于一个线性方程,未知函数和其导数只以线性的形式出现(加减),不与其他函数相乘除或作为其他函数的参数 更正式的说,令...

Partial Differential Equations through Examples and Exercises Endre Pap, Arpad Takači & Djurdjica Takači Part of the book series: Kluwer Texts in the Mathematical Sciences ((TMS,volume 18)) 1129 Accesses Abstract A first order PDE is an equation of the form {Eq 17_2.1} where F is...
First-Order PDE: The method of characteristicsAnton Dzhamay
Antonio2012년 9월 25일 0 링크 번역 I'm trying to solve the following equation using PDEPE: dC/dt + v * dC/dx = constant With the boundary conditions: C(t,0)=Cin dC(t,L)/dx=0 My question is how can I incorporate the second BC in the PDEPE syntax, if I should de...
Conversion of High Time Order PDE to First Order Description Examples Description As mentioned on the pdsolve/numeric page, before numerical solution of time based PDE systems containing higher than first order derivatives, the system is converted to...
We shall discuss in this paper the existence of solutions and the finite dimensionality of the solution space for overdetermined systems of linear pde's of first order of generic type. Our approach is from the viewpoint of exterior dierential system. By prolongation to a complete system we set...

This paper concentrates on a particular first-order coupled PDE system. It provides both a detailed treatment of the existence and uniqueness of monotone travelling waves to various equilibria, by differential-equation theory and by probability theory and a treatment of the corresponding hyperbolic initi...
