the reaction-diffusion equation with stiff source term: au(1- u). These schemes have the properties that they reduce to high fidelity algorithms in the diffusion- free case namely in which the numerical solutions preserve the properties inherent in the exact solutions for arbitrary time step-size...

若未知函数是二元及以上的,那么则是偏微分方程(partial differential equation (PDE) ),如(1.3) 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...
Cauchy-Euler equationWe consider first and second order linear dynamic equations on a time scale. Such equations contain as special cases differential equations, difference equationsq difference equations, and others. Important properties of the exponential function for a time scale are presented, and ...
The second-order supersonic flow can then be computed with slight modification of the Karman-Moore procedure. For inclined flow, no particular solution of the second-order equation has been discovered. The second-order solution is derived for a cone, and agrees well with the exact solution. ...
