Main article: Fundamental solution Inhomogeneous equations can often be solved for constant coefficient PDEs, always be solved by finding the fundamental solution the solution for a point source , then taking the convolution with the boundary conditions to get the solution. This is analogous in signal processing to understanding a filter by its impulse response. Further information: Superposition principle The superposition principle applies to any linear system, including linear systems of PDEs. The same principle can be observed in PDEs where the solutions may be real or complex and additive. Methods for non-linear equations[ edit ] See also: nonlinear partial differential equation There are no generally applicable methods to solve nonlinear PDEs.

Partial differential equation

Methods for non-linear equations[ edit ] See also: nonlinear partial differential equation There are no generally applicable methods to solve nonlinear PDEs. Still, existence and uniqueness results such as the Cauchy—Kowalevski theorem are often possible, as are proofs of important qualitative and quantitative properties of solutions getting these results is a major part of analysis. Nevertheless, some techniques can be used for several types of equations. The h-principle is the most powerful method to solve underdetermined equations.

The Riquier—Janet theory is an effective method for obtaining information about many analytic overdetermined systems. The method of characteristics can be used in some very special cases to solve partial differential equations.

In some cases, a PDE can be solved via perturbation analysis in which the solution is considered to be a correction to an equation with a known solution. Alternatives are numerical analysis techniques from simple finite difference schemes to the more mature multigrid and finite element methods. He also emphasized the subject of transformations of contact.

A general approach to solving PDEs uses the symmetry property of differential equations, the continuous infinitesimal transformations of solutions to solutions Lie theory. Symmetry methods have been recognized to study differential equations arising in mathematics, physics, engineering, and many other disciplines. Semianalytical methods[ edit ] The adomian decomposition method , the Lyapunov artificial small parameter method, and He's homotopy perturbation method are all special cases of the more general homotopy analysis method.

These are series expansion methods, and except for the Lyapunov method, are independent of small physical parameters as compared to the well known perturbation theory , thus giving these methods greater flexibility and solution generality.

Numerical solutions[ edit ] The three most widely used numerical methods to solve PDEs are the finite element method FEM , finite volume methods FVM and finite difference methods FDM , as well other kind of methods called Meshfree methods , which were made to solve problems where the before mentioned methods are limited.

The FEM has a prominent position among these methods and especially its exceptionally efficient higher-order version hp-FEM. Finite element method[ edit ] Main article: Finite element method The finite element method FEM its practical application often known as finite element analysis FEA is a numerical technique for finding approximate solutions of partial differential equations PDE as well as of integral equations.
