In mathematics, the Cauchy principal value, named after Augustin Louis Cauchy, is a method for assigning values to certain improper integrals which would otherwise be undefined. (Wikipedia).
Real numbers as Cauchy sequences don't work! | Real numbers and limits Math Foundations 114
This longish video lays out the various reasons why Cauchy sequences---as a basis for the theory of real numbers---don't work. Necessary viewing for all maths students! We really need to start addressing the logical weaknesses, rather than pretending that they are not there! Video Conten

Cauchy principal value integral example. You learn in calculus courses that an improper integral is sometimes divergent, but in this video I show you how to make it (rigorously) equal to zero! This is widely used in distribution theory and Fourier analysis Subscribe to my channel: https:

Intro to Cauchy Sequences and Cauchy Criterion | Real Analysis
What are Cauchy sequences? We introduce the Cauchy criterion for sequences and discuss its importance. A sequence is Cauchy if and only if it converges. So Cauchy sequences are another way of characterizing convergence without involving the limit. A sequence being Cauchy roughly means that

Cauchy Sequence In this video, I define one of the most important concepts in analysis: Cauchy sequences. Those are sequences which "crowd" together, without necessarily going to a limit. Later, we'll see what implications they have in analysis. Check out my Sequences Playlist: https://w
