THE EQUIVALENCE PROBLEM FOR A CLASS OF LINEAR FOURTH-ORDER TELEGRAPH EQUATIONS
Mostafa Hesamiarshad and Mehdi Nadjafikhah
|
Abstract:
The moving coframe method is applied to solve the local equivalence problem for a class of linear fourth-order telegraph equations, in two independent variables under action of a pseudo-group of contact transformations to determine necessary and sufficient conditions for a class of linear fourth-order telegraph equations to be equivalent to simplest model under a contact transformation. |
| Keywords and phrases: contact transformations, equivalence problem, linear fourth-order telegraph equations, moving coframe. |
