Solutions of Laplace's equation are called harmonic functions; they are all analytic within the domain where the equation is satisfied. If any two functions are solutions to Laplace's equation (or any linear homogeneous differential equation), their sum (or any linear combination) is also a solution. Laplace's equation and Poisson's equation are the simplest examples of elliptic partial differential equations. The general theory of solutions to Laplace's equation is known as potential theory. The solutions of Laplace's equation are the harmonic functions, which are important in many fields of science, notably the fields of electromagnetism, Are you familiar with logarithms? Using logs, you can change a problem in multiplication to a problem in addition. More useful, you can change a problem in exponentiation to one in multiplication.

Example 1: Harmonic oscillator x˙ = 0 1 −1 0 x ... Solution via Laplace transform and matrix exponential 10–15. however, we do have eA+B = eAeB if AB = BA, i.e ... Again, Poisson’s equation is a non-homogeneous Laplace’s equation; Helm-holtz’s equation is not. Laplace introduced the notion of a potential as the gradient of forces on a celestial body in 1785, and this potential turned out to satisfy Laplace’s equation. Then other applications involving Laplaces’s equation came along, The Laplace equation is also a special case of the Helmholtz equation. The general theory of solutions to Laplace's equation is known as potential theory. The solutions of Laplace's equation are the harmonic functions, which are important in branches of physics, notably electrostatics, gravitation, and fluid dynamics.

Harmonic functions—the solutions of Laplace’s equation—play a crucial role in many areas of mathematics, physics, and engineering. But learning about them is not always easy. At times the authors have agreed with Lord Kelvin and Peter Tait, who wrote ([18], Preface) There can be but one opinion as to the beauty and utility of this

Jun 17, 2017 · The Laplace transform is an integral transform that is widely used to solve linear differential equations with constant coefficients. When such a differential equation is transformed into Laplace space, the result is an algebraic equation, which is much easier to solve. A function which satisfies Laplace's equation is said to be harmonic. A solution to Laplace's equation has the property that the average value over a spherical surface is equal to the value at the center of the sphere (Gauss's harmonic function theorem). Solutions have no local maxima or minima.
