May 01, 2020 · The canonical form of a hyperbolic equation is [ ] [ ] , (17) or, ( ) (17a) where in (17) is a first-order linear differential operator, and is a function that have been clubbed together in (17a) as where . This form is called the first canonical form of the hyperbolic equation. We also have another simple

4. Canonical or standard forms of PDE's 4.1. Three Canonical or Standard Forms of PDE's Every linear 2nd-order PDE in 2 independent variables, i.e., Eq.(1) can be converted into one of three canonical or standard forms, which we call hyperbolic, parabolic or elliptic. Written in new variables ξ and η, the three forms are: uξξ - uηη + …. = 0

The PDE is parabolic and the characteristics are to be found from the equation: ξ x 2 + 2 ξ x ξ y + ξ y 2 = ( ξ x + ξ y) 2 = 0. You can solve for ξ x / ξ y as follows: ξ x ξ y + 1 = 0 ⇒ ξ x ξ y = − 1 = − d y d x, and hence you have information of only one characteristic since the solution of the equation above is double: ξ ...
