Hello, I am trying to understand some principles in my book.(adsbygoogle = window.adsbygoogle || []).push({});

Is the lowering operator [tex]A[/tex], the conjugate of the raising operator [tex]A^{+}[/tex]?

Also I was reading that the lowering operator [tex]A[/tex] is not Hermitian since it and its adjoint [tex]A^{+}[/tex] are not equal? Does that imply that [tex]A^{+}[/tex] is not Hermitian.

Thank you.
