WebApr 7, 2024 · It is tedious to take the Laplacian of the fundamental Green's functions. It is no more tedius to take the Laplacian of each term of the Green's function in (1). One can take the Laplacian by hand or with a symbolic software package. Needless to say, both the fundamental Green's function and Green's function here satisfy the first requirement. The primary use of Green's functions in mathematics is to solve non-homogeneous boundary value problems. In modern theoretical physics, Green's functions are also usually used as propagators in Feynman diagrams; the term Green's function is often further used for any correlation function. Framework Let … See more In mathematics, a Green's function is the impulse response of an inhomogeneous linear differential operator defined on a domain with specified initial conditions or boundary conditions.
