Definition from my textbook: For each linear operator T on a inner product space V, the adjoint of T is the mapping T* of V into V that is defined by the equation <T*(v),w> = <v,T(w)> for all v, w E V.
My instructor defined it by <T(v),w> = <v,T*(w)> and he said that these 2 definitions are equivalent.
Now, can someone please explain WHY they are equaivalent?
Can both definitions be used at the SAME time, or do I have to choose 1 of the 2 definitions and use this chosen definition consistently everywhere?
Thanks for explaining!
