lol thanks. I was worried I was being completely thick then. don't suppose you have a link do you for where I can see it for free? can't find it.
Im generally confused on this whole matter. Ultimately I want to perform a super poincare transformation on superspace. I.e a susy transform then a...
Then now I really do not understand. In order to maintain covariance the following expression is true.
S_{-1}(\Lambda)\gamma^{\mu} S(\Lambda)=\Lambda^{\mu}_{\nu}\gamma^{\nu}
if we write a lorentz transformation on a spinor as \psi'(x')=S(\Lambda)\psi(x)=S(\Lambda)\psi(\Lambda_{-1}x')
then say...
I'm very confused
By performing a lorentz transformation on a spinor \psi\rightarrow S(\Lambda)\psi(\Lambda x) and imposing covariance on the Dirac equation i\gamma^{\mu}\partial_{\mu}\psi=0 we deduce that the gamma matrices transform as
S(\Lambda)\gamma^{\mu}...
I'm currently trying to read a paper and it's not making much sense. Don't feel I expect anyone to read it in detail but it might give you an idea of the lack of understanding I am having. In all honesty I don't think it's terribly well written, coupled with the fact that I'm thick and only half...
I have a six dimensional lie algebra. I checked it was semi-simple by checking if the killing form was not invertible. I found a set of two (I think) maximally commuting elements which I called H1 and H2 and found their matrix representation by calculating the structure constants.
I have put...
say I have a set of basis vectors of a vector space v1, v2...vn and some element of the vector space, say V
What command do I use in maple to calculate the coordinates of V in this basis? I can't find one in the linalg package
Hi again, I could really use some help on this please.
I have also realized T1+T2+T3=0.
I do not understand. Does this mean g1+g2+g3=0. I do not believe this at all.
What matters most in a car is the following...
a) Fuel economy and emisions
b) crash worthyness
c) reliability
What you want is the most uneconomical and polluting car there is, something with a big dirty V8 or something. No electronics or high tech stuff. Just basic engine, gearbox and wheels...
I have a lie algebra whose killing form is degenerate, hence not semi simple by cartan's second criterion.
So I cannot apply a Cartan Weyl Basis to classify the algebra. I currently have an algebra with 5 generators. Later I will have one with 11 generators and I am hoping I can spot how i...
yes group multiplication.
I don't know why it's specifying closed subgroup to be honest. The word is redundent.
Yes I didn't bother with associativity but at this time in the evening I couldn't be arsed lol
