44: Integral transforms, operational calculus


Integral transforms include the Fourier transform (see section 43) as well as the transforms of Laplace, Radon, and others. (The general theory of transformations between function spaces is part of Functional Analysis, section 46) Also includes convolution operators and operational calculi.
