Ok, so I have some QM notation questions. I am not a physics student so I am not 100% sure what all the different symbols mean. I am working from Lie Algebras and Particle Physics by Georgi and he does not offer a key for all the symbols.(adsbygoogle = window.adsbygoogle || []).push({});

Let A be a matrix representing a linear operator. Ok, what is the difference between A* and A^(dagger looking symbol).

I've seen A* mean the conjugate transpose and A-dagger to be conjugate transpose. I've also seen A* to be transpose.

So in terms of QM, what do these notations mean? What about when you are taking the trace of A, tr(A), but then you put tr(A)*??

Thanks
