and H(t) = 1 for t > 0. (The value at t = 0 is not important, but most often is assumed to be 1/2.) The last inverse Fourier trasform is accomplished by using the usual technique of integrating over a closed contour in the plane of complex ω around the pole at −i∆ and taking a residue. Note that the Fourier transform between F2(t) and F˜2 ...

Suppose there exists an n×n matrix B such that AB = BA = In. Then the matrix A is called invertible and B is called the inverse of A (denoted A−1).
