WebBy the way, I read a statement. Accourding to the statement, " in order to be homogeneous linear PDE, all the terms containing derivatives should be of the same order" Thus, the first example I wrote said to be homogeneous PDE. But I cannot understand the statement precisely and correctly. Please explain a little bit. I am a new learner of PDE.

The nonlinear equations contain, as special cases, several PDEs such as Burgers equation, nonlinear-Schrödinger equation (NLSE), Korteweg–De Vries (KDV) equation, …
WebFundamentals of Partial Differential Equations We’ll first examine the motivation for studying PDEs, then examine their nature and classification, and finally talk about various solution methods. Recall that the basic attribute of a PDE is that it has two or more independent variables. In most applications these represent time and space.
