In the West Coast convention, as far as space goes, you have decided to work with a negative definite metric, which is a quite misguided thing to do for obvious reasons. However standard textbooks like Landau, Bjorken-Drell or Itzykson-Zuber, leave the -i factor next to the derivative and so the Dirac operator is shares. West Coast Metric definition, categories, type and other relevant information provided by All Acronyms. As I tried to point out, one virtue of the conventions I advocate is that you can choose the gammas real. CARS ARE JUST THE BEGINNING. What Zee says would be correct if you complexify the two Lie algebras: what is true is that the complexified Lie algebra of SO(3,1) is the same as the complexified Lie algebra of the product of two copies of SU(2).

Weinberg’s quantum field theory textbook uses the East Coast convention. This is not true for real Lie algebras, which is what the notation he is using refers to (if you ignore the fact that he’s using the notation for Lie groups to refer to Lie algebras…) My point was just that for him and Schwartz (and a lot of physicists), there is no difference between a real Lie algebra and its complexification. Unlike the p^2=-m^2 which appears everywhere where particle dynamics is considered. At least 1,962 new coronavirus deaths and 201,723 new cases were reported in the United States on Dec. 21.

This creates very strange things, such as in that universe the speed of light varies with the frequency and that the “twin paradox” is upside down (time goes by faster with the twin that remains at home), among many many other things.

When you complexify a real Lie algebra so(p,q), you get something that doesn’t depend on the signature (so(q+p,C)), since once you have complexified you can just appropriately put in factors of i to make your inner product the standard one. After purchasing a house in Cowichan Bay in 2004, we knew this was home. After purchasing a house in Cowichan Bay in 2004, we knew this was home.

If you’re doing calculations in relativistic quantum field theory, you typically handle the Minkowski nature of space-time by introducing an indefinite signature metric, and there are two possible choices: While I was educated on the East Coast, most courses I took and textbooks I used favored the West Coast metric, and that’s very much true of more recent textbooks (I don’t know of a recent one using the East Coast convention). Did Zee complexify the SO(3,1) in the book such that his statement is correct contextually, or is the excerpt you are showing simply wrong mathematically and not deducible from the introduction?
