Hi guys, getting a little confused whilst looking through a paper. I was hoping someone could clear this up for me quickly;(adsbygoogle = window.adsbygoogle || []).push({});

If we have a matrix denoted by the following, which is both real and unitary;

A_{mn}

then is the following true (due to it being real, the conjugate just produces the same thing);

A_{mn}^{*}= A_{mn}

However, if we dagger A, the indices change like the following;

A_{mn}^{+}= A_{nm}

I think I'm getting confused because i expected both the conjugate and the dagger to do the same thing...

I am trying to get to grips with the paper, but some of the summation notation to represent matrices is confusing me. Any good reads someone could recommend to help with this would be great. Otherwise confirmation of what I've previously said would be amazing.

thanks in advance!
