Equations with Finite-Dimensional Solution Space,constants. In other words, its general solution has the structure of a finite-dimensional vector space over constants like in the ordinary case. At first the Loewy decomposition of such systems in two independent variables containing derivatives of order not higher than three are discussed. Subsequently they are applied for finding its solutions.

Solving Homogeneous Third-Order Equations,he structure of the solutions of linear pde’s on page 91 apply here as well. Similar as for second-order equations, various cases differing by leading derivatives are distinguished. As opposed to second-order equations, third-order equations have virtually never been treated in the literature before.
