Distribution Theory by Riemann Integrals. (arXiv:1810.04420v1 [math.FA])
来源于:arXiv
It is the purpose of this article to outline a course that can be given to
engineers looking for an understandable mathematical description of the
foundations of distribution theory and the necessary functional analytic
methods. Arguably, these are needed for a deeper understanding of basic
questions in signal analysis. Objects such as the Dirac delta and Dirac comb
require a proper definition, and it should be possible to explain how one can
reconstruct a band-limited function from its samples by means of simple series
expansions. It should also be useful for graduate students who want to see how
functional analysis can help to understand fairly practical problems, or
teachers who want to offer a course related to the "Mathematical Foundations of
Signal Processing". The course requires only an understanding of the basic
terms from linear functional analysis, namely Banach spaces and their duals,
bounded linear operators and a simple version of weak$^{*}$-convergence. As a
