Determined to finish off my assignment!
Firstly, it's 2:50 am here and I'm NOT going to sleep until I finish this assignment off! I have few remaining ones and I'd be glad if someone could help me out so I can go to sleep...
Please consider this question(and the one I posted below)...
I don't know if there's anyone who bother to answer my questions but still let me try..
If function f:R^2-->R is f(x,y)=0 if (x,y)=(0,0) and xy^2/(x^2+y^2) otherwise, then prove that f is not continuous at (0,0)
Supposed to be easy but my brain is dead right now for this..
it's multivariable...
hey,

Q1. If j = square root of - 1 what is square root of j ?
what I did was : Plug in the value of j in square root of j and came up with -1 to the power of 0.25.
Is this right. Looks like this wrong.
Q2. Given a complex number w = x + jy, the complex congugate of w is defined in...
[URGENT]How to prove gluon has this quantum number assignment?
From PDG booklet, for gluon, I^G(J^{PC}) = 0(1^-).
My questions are:
1. How to prove its P=-1?
2. Why C parity and therefore G parity are not well-defined for a gluon?
Is it because gluon have nothing to do with...
Ive seen questions like this one done here before but I don't think I am understanding this well. The question is:
