    Excellent summary. Functional analysis is essentially the linear algebra of infinite-dimensional spaces. Highlighting the failure of the Heine-Borel property and the unbounded nature of differentiation correctly identifies the core challenges of modern analysis

    This is the first video that I've seen from your channel and I'm very impressed. You've managed to make your presentation interesting and have also allowed the viewer to see why they may want to learn some functional analysis by the nice comparisons to linear algebra, pointing out where it fails in the infinite dimensional case. There are many books that fail to do this, plunging into a topic with no motivation nor any sense of the historical development of the subject.

    Excellent presentation, I can't think of other explanations that are so good as yours.

    この放送は、基礎レベルの線形代数だけ理解している者にも、関数解析の必要性を分かりやすく説明していると思う。素晴らしい。

    this is connecting a lot of dots for me that I&apos;ve loosely held but never formed the comprehensive picture. Thanks for building this lecture.

    Absolutely beautiful topic. &nbsp;The richness only increases with time.

    Absolutely mindblowing content. This really put together so many different pieces of linear algebra and (functional) analysis and how it relates to applications as well.

    Excellent explanation thanks …

    I hope you&apos;ll discuss spectra of operators and the notion of continuous spectra in future lectures because I&apos;m still confused about these!
