A guide to analytic methods in applied mathematics from the perspective of functional analysis, suitable for scientists, engineers and students.
Presents an easily-accessible discussion of analytical methods of applied mathematics from vector spaces to distributions, Fourier analysis, and Hardy spaces with applications to system theory; and an introduction to modern functional analytic methods to better familiarize readers with basic methods and mathematical thinking.
