MIT 18.102 Introduction to Functional Analysis, Spring 2021 Instructor: Dr. Casey Rodriguez View the complete course: https://ocw.mit.edu/courses/18-102-introduction-to-functional-analysis-spring-2021/ YouTube Playlist: https://www.youtube.com/watch?v=TXMCTAF6SEE&list=PLUl4u3cNGP63micsJp_--fRAjZXPrQzW_&index=10 We define simple functions: the basic building blocks for the Lebesgue integral. We then prove some basic properties of the Lebesgue integral for simple functions, which we use next time to extend integration to certain measurable functions.
