Описание: | The theory of distrubutions is usually presented in close connection with functional analysis, and the prehistory of that theory adds a very important element to the history of functional analysis. The problems or theories which shaped the prehistory of the theory of distributions are: 1. Heaviside's operational calculus; 2. Generalized derivatives and generalized solutions to differential equations; 3. Generalized Fourier transforms; 4. Improper functions; the a-functions and the partie finie; 5. The Rhams's currents. Why is the theory of distributions important? For what purpose was the theory of distributions originally created? Who invented distributions and when? You could find the answers and new questions in Lecture Notes. |
