Abstract:

An operator $T$ on a complex Hilbert space $\mathcal {H}$ is said to be skew symmetric if there exists a conjugate-linear, isometric involution $C:\mathcal {H}\longrightarrow \mathcal {H}$ so that $CTC=-T^*$. In this paper, we shall give two structure theorems for skew symmetric normal operators.
