First-Order Partial Differential Equations the case of the first-order ODE discussed above. Clearly, this initial point does not have to be on the y axis. If the values of uΩx, yæ on the y axis between a1 í y í a2 are given, then the values of uΩx, yæ are known in the strip of the x-y plane with a1 í y í a2.

The linear equation (1.9) is called homogeneous linear PDE, while the equation Lu= g(x;y) (1.11) is called inhomogeneous linear equation. Notice that if uhis a solution to the homogeneous equation (1.9), and upis a particular solution to the inhomogeneous equation (1.11), then uh+upis also a solution to the inhomogeneous equation (1.11).

17.2 First Order Homogeneous Linear Equations
https://www.whitman.edu/mathematics/calculus_online/section17.02.html
Definition 17.2.1 A first order homogeneous linear differential equation is one of the form y ˙ + p ( t) y = 0 or equivalently y ˙ = − p ( t) y . "Linear'' in this definition indicates that both y ˙ and y occur to the first power; "homogeneous'' refers to the zero on the right hand side of the first form of the equation.

In this case, the operator can be factored (just like a binomial expression) in the following way: A = ( ∂ ∂ t + 3 ∂ ∂ x) ( 3 ∂ ∂ t + ∂ ∂ x). Now, change the variables such that each of the two factors will be a partial derivation. ∂ ∂ y = ( ∂ ∂ t + 3 ∂ ∂ x), ∂ ∂ z = ( 3 ∂ ∂ t + ∂ ∂ x)
