#### Green’s Functions

12.3 Expression of Field in Terms of Green’s Function Typically, one determines the eigenfunctions of a diﬀerential operator subject to homogeneous boundary conditions. That means that the Green’s functions obey the same conditions. See Sec. 11.8. But suppose we seek a solution of (L−λ)ψ= S (12.30) subject to inhomogeneous boundary

The Green''s function is then a kind of inverse of L. y(x)= In Maple it looks like this. > part_sol:=Int(G[s,x]*f(x),x); (9) Once we know the Green''s function for a differential operator L, we may solve the equation for any function on the right side by substitution in the above expression. Ex. 1. Find the general solution of

#### Introduction to Green’s Functions: Lecture notes1

Green’s functions provide a powerful tool to solve linear problems consisting of a diﬀerential equation (partial or ordinary, with, possibly, an inhomogeneous term) and enough initial- and/or boundary conditions (also possibly inhomogeneous) so that this problem has a unique solution. The Green’s function is deﬁned by a similar problem

Green''s Functions in Physics. Green''s functions are a device used to solve difficult ordinary and partial differential equations which may be unsolvable by other methods. The idea is to consider a differential equation such as. d 2 f ( x) d x 2 + x 2 f ( x) = 0 ( d 2 d x 2 + x 2) f ( x) = 0 L f ( x) = 0.

#### Green''s function (many-body theory) - Wikipedia

In many-body theory, the term Green''s function (or Green function) is sometimes used interchangeably with correlation function, but refers specifically to correlators of field operators or creation and annihilation operators.. The name comes from the Green''s functions used to solve inhomogeneous differential equations, to which they are loosely related.
