 [YT] One parameter groups of transformations, vector fields and differential operator MphLee Long Time Fellow Posts: 270 Threads: 23 Joined: May 2013 06/15/2021, 09:31 PM Daniel Chan Maths - 1-parameters groups and vector fields I bring to the forum the last vid of Prof. Daniel Chan's (UNSW, Sydney, Australia) amazing channel. I just leave here as bookmark an interesting lesson on this topic. Maybe this material is know to everyone hereĀ  but I hope it will be an useful resource for future users. It was enlightening for me for sure, since it touches alot of recent discussion in a more unified and standard way.

God, I hate real-analysis; and vector space mumbo jumbo. That's why I invented the compositional integral. Always nice to see the equivalent structure though. But all I felt through that video was: everything should be holomorphic and in $\mathbb{C}$; lol. And! it should be non-abelian $s\bullet t$ not $s + t$. Good video though.
