 Jun11 accepted What is the Lie algebra of the Galilean group and what is the structure of it? Jun8 comment What is the Lie algebra of the Galilean group and what is the structure of it? Thank you, this is very helpful. Jun8 asked What is the Lie algebra of the Galilean group and what is the structure of it? Jun5 comment Why Liouville's theorem is obvious? @RonMaimon: A double-check of the author's proof verified your claim, thanks. Jun3 comment Why Liouville's theorem is obvious? @RonMaimon: I mean by realizing the determinant is 1, the proof just follows. It is easier than working with the mixed partial derivatives. Jun3 comment Why Liouville's theorem is obvious? Thanks! (I realized this myself). Jun3 accepted Why Liouville's theorem is obvious? Jun3 comment Why Liouville's theorem is obvious? @RonMaimon: Thanks, did as you suggested. Jun3 answered Why Liouville's theorem is obvious? Jun2 awarded Editor Jun2 revised Why $\frac{d}{dt}r_{a}\nabla_{a}U_{ab}+\frac{d}{dt}r_{b}\nabla_{b}U_{ba}=\frac{d}{dt}U_{ab}?$ corrected the book name Jun2 awarded Supporter Jun2 comment Why Liouville's theorem is obvious? @Ron Maimon: This is helpful, but not so transparent to a layman like me (who learned Possion bracket yesterday). So I have to spend some time to understand this. Thanks for the help. Jun2 awarded Scholar Jun2 comment Why $\frac{d}{dt}r_{a}\nabla_{a}U_{ab}+\frac{d}{dt}r_{b}\nabla_{b}U_{ba}=\frac{d}{dt}U_{ab}?$ Thanks! This is helpful .
