Question

Can anyone help me with complex conjugates. What are the properties of it.

Answer 1

\[(A)^{*}\]
For example what it we multiply it with a constant? What about with a variable x
\[(xA)^{*}\]
\[(aA)^{*}\]
Where a is a constant can we simplify this?

Answer 2

I'm doing hermitian operators but the only problem I have is how to treat the complex conjugate inside an integral.

Answer 3

x is complex?

Answer 4

no

Answer 5

you can take a or out so

Answer 6

x*

Answer 7

\[(a.(x+yi))*=a.x-a.yi=a(x-yi)=a.(x+yi)* \]

Answer 8

ok what if you have\[ (\phi d/dx\ )^{*} \]

Answer 9

where phi is a function.

Answer 10

y think you can do the same
