I have hyperlinked more of the technical terms (such as Hodge star operator) and also made explicit some more technical terms used in the formulas (such as dual vector space)
]]>I added another explanation of why Spin(6) is SU(4).
I should do the same sort of thing for Spin(5) and Spin(4).
]]>I have added the picture of Dynkin diagrams that illustrates the exceptional iso (here). Am adding this also at SU(4) and at A3
]]>am giving this its own little entry (in line with Spin(2), Spin(3), Spin(4), Spin(5)). For the moment just as to record a nice reference for the exceptional iso
