Positive non self adjoint operator?

Click For Summary
SUMMARY

The discussion centers on identifying a positive non-self-adjoint operator T on F^2, where the inner product is non-negative for all vectors v in F^2. The participants suggest exploring rotations as potential examples of such operators. The conversation emphasizes the need for algebraic manipulation to derive all possible values of T that satisfy the given condition while remaining non-self-adjoint.

Can't you use algebra to solve for all possible values of T?
