1. The problem statement, all variables and given/known data Show that if an operator A has an eigenket |a> to eigenvalue a then the adjoint operator A† has an eigenbra <a*| to eigenvalue a*. How is <a*| related to |a>? 2. Relevant equations A|a> = |a>a | >† = < | 3. The attempt at a solution I actually have no clue where to start this question. I am guessing it has something to do with A† would have an eigenket of |a>†. But I am unsure if this is correct at all. Would anyone be able to help me get started.
