In this article, we establish some relationships between several types of partial differential equations and ordinary differential equations. One application of these relationships is that we can get the exact values of the blowup time and the blowup rate of the solution to a partial differential ...
A differential equation is an equation that contains at least onederivativeof an unknown function, either an ordinary derivative or a partial derivative. Suppose the rate of change of a function y with respect to x is inversely proportional to y, we express it as dy/dx = k/y. Incalculus,...

Order and degree (if defined) of a differential equation are always positive integers. Types of Differential Equations Differential equations can be divided into several types namely Ordinary Differential Equations Partial Differential Equations Linear Differential Equations ...
active (likeinductorsandcapacitors) and passive parameters (resistor) are assumed to be distributed uniformly along the length and that’s why these are called distributed parameter type of system. Analysis of such type of system is slightly difficult which includes partial differential equations....

Actually the basic concept of "type" of a partial differential equation is based on the simplified form that you started with. Any equation of the form Auxx+ Buyy= something is "elliptic", A and B are numbers of the same sign. Any equation of the form Auxx- Buyy= something is "...
This leads to a system of fourth-order degenerate parabolic partial differential equations. We derive these equations from balance laws, show some properties... CM Elliott,H Garcke - 《Physica D-nonlinear Phenomena》 被引量: 166发表: 1997年 The Evans Function and Generalized Melnikov Integrals non...
