Title: Horrible
Product review: It doesn't take a lot of intelligence to figureout how to present lie algebras and lie groupsif you are going to take the matrix route.Namely, you give lots of concrete examples(requiring nothing more than calculus asbackground) and then just state what the generalcase is. In this book, the author uselessly dragsthe uninitiated through swamps of archaic notation(save that for the real thing) and incompleteproofs (where invariably the hard parts are just quoted)so that you have to wonder what in the world is the pointof committing this mess to paper. It is ironic that thevery same publisher already has better books out on exactlythe same topics. Finally, if this really were an introductionyou wouldn't have to add 'elementary' to the title - so let'scall a spade a spade and leave the spin to the politicians.
Would you say this review depicts the product in a flattering or unflattering light?
