Lecture

Fourier Transform and Schwartz Space

Description

This lecture covers the connection of a free quantum particle to the Fourier transform, the definition of the Fourier transform on L^1, the Riemann-Lebesgue lemma, and the definition of Schwartz space as a complete metric space. The instructor explains the importance of the Fourier theory in understanding quantum particles and time-dependent Schrödinger equations. The lecture also delves into the properties of Schwartz space and its role in defining functions in L^2. The Riemann-Lebesgue lemma is introduced as a key tool in Fourier analysis. The presentation progresses through the basic properties of Schwartz space and the metric space defined by the Fourier transform.
