As an occupation, I'm a mathematical physicist, studying string theory and quantum field theory.

I've developed as a hobby a few Cocoa (Touch) apps. The largest one so far is spires.app, which manages articles and metadata downloaded from the arXiv eprint server, the inspire database, and the journal websites.

I'm also interested in many other things, which is why I ask questions in various StackExchange sites ...

comment Automatically convert \left to \Bigl
Thanks! Is there a way to do the redefinition of \big etc automatically? I guess I should ask it as a separate question, as is customary in Stack Exchange...

@Fritz: I have a code I wrote in Mathematica, which does P2 :p Does it help posting the code here?

Well TeX can't prevent the coming Apocalypse, for example...

comment How can I replicate affine Dynkin diagrams in Kac's textbook?
Amazing!!! Thank you very much for the TeX code. Is it OK for me to include them into the paper on this subject? Well I don't know whether and when it ever becomes complete, though. They look beautiful!

comment How can I replicate affine Dynkin diagrams in Kac's textbook?
This is fantastic, thank you very much @Andrew. As for the quadruple arrow, looking at the book carefully, it might be that the publisher added lines by hand after TeX typesetting is done ...

Thank you too! It's very nice and simple for linear diagrams.

comment How can I replicate affine Dynkin diagrams in Kac's textbook?
@Antal, it's OK if it looks the same; but I'm also interested how he or the typesetter did it long time ago when it was published.

comment How can I replicate affine Dynkin diagrams in Kac's textbook?
@Andrew: I'm fine with that. If the spacing is nicer, that would be even better. I really liked Kac's "minimalism", in the sense that he used only what's simply available in AMSTeX, like \circ, \cdots, standard minus sign, and \Leftarrow. So I'd like to replicate that.

comment How can I replicate affine Dynkin diagrams in Kac's textbook?
That's not my essential point; my point is to reproduce what Kac has in his textbook. I changed the title of the question after @Joseph Wright gave me the comment. Indeed I didn't express my intent correctly.

comment How can I replicate affine Dynkin diagrams in Kac's textbook?
I guess when Kac's book was written pgf/TikZ was not available; shouldn't there be an elementary way? I like the way Kac used the standard arrows which is part of math fonts, not the generated arrows in XyPic or pgf. The triple arrow comes with AMSTeX, it's called \Lleftarrow and \Rrightarrow.

Sorry for looking like a dupe, but I really want to reproduce the Table in this textbook: books.google.co.jp/…
