Green's function (GF) is a fundamental solution to a linear differential equation, a building block that can be used to construct many useful solutions. For heat conduction, the GF is proportional to the temperature caused by a concentrated energy source. The exact form of the GF depends on the differential equation, the body shape, and the type of boundary conditions present. Green's functions are named in honor of English mathematician and physicist George Green (1793-1841).
