Polyharmonic Functions

Definition

Let Δ=2\Delta = \nabla^{2} be called a Laplacian. For a natural number kNk \in \mathbb{N}, Δk\Delta ^{k} is referred to as a polyharmonic operator or a polylaplacian. The equation below is called the polyharmonic equation.

Δkf=0 \Delta^{k} f = 0

The solutions to the polyharmonic equation are referred to as polyharmonic functions.

Description

It is a generalization of harmonic functions.
