I was comparing two lectures about SU(5) grand unified theory.
- a lecture of Susskind
He showed how to write
(5×5)asym=¯10
as

- a lecture of Zee showed how to write
(ˉ5×ˉ5)asym=10
as

Other than the difference between
(5×5)asym=¯10 versus (ˉ5×ˉ5)asym=10
My question is that there is also an extra minus sign in Zee's notation? See the
−ˉu
in the 1st row and the 3rd column. I suppose Zee is correct and Susskind missed a minus sign or more signs. Am I understanding it correct?
