Greens function problems
WebProblems with inhomogeneous BCs 1. Green’s Functions (introduction) We return to solving boundary value problems (BVPs), introducing an approach that uses integral equations of a sort rather than eigenfunctions. It is one of the main techniques for solving BVPs and PDEs, and plays an important role in physical problems where the WebWe employ Green’s function method for describing multiband models with magnetic impurities and apply the formalism to the problem of chromium impurities adsorbed onto a carbon nanotube. Density functional theory is used to determine the bandstructure, which is then fit to a tight-binding model to allow for the subsequent Green’s function description.

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. Let be the Sturm–Liouville operator, a linear differential operator of the form WebJul 9, 2024 · The function G(x, ξ) is referred to as the kernel of the integral operator and is called the Green’s function. We will consider boundary value problems in Sturm-Liouville form, d dx(p(x)dy(x) dx) + q(x)y(x) = f(x), a < x < b, with fixed values of y(x) at the …
