Let $\HH$ be a Hilbert space.

Let $\mathbf T: \HH \to \HH$ be a bounded linear operator.

Then $\mathbf T$ is said to be Hermitian if and only if:

$\mathbf T = \mathbf T^*$

That is, if and only if it equals its adjoint $\mathbf T^*$.

Also known as

A Hermitian operator is also known as a self-adjoint operator.
