Solution of a differential equation with an impulse as the exciting force. Exact seismograms in a given medium can be viewed as the convolution of the source wavelet and the medium’s Green’s function. See *convolutional model*.

Problems in the physical sciences consist of a *governing equation,* which may be an ordinary differential equation (ODE)
or a partial differential equation (PDE), a *source* or forcing function for the equation, and a set of *boundary conditions.*
When the governing equation is a linear operator, many such problems may be solved via the so-called Green's function method.
