Let $T:\ell^2\rightarrow \ell^2$ be defined by $T(\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...)\rightarrow (0,0,\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...)$.Is $T$ Self Adjoint?Is $T$ Bounded?

$T$ is Self-Adjoint

$\langle T(\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...),(\eta_1,\eta_2,\eta_3,\eta_4,...)\rangle$

=$\langle(0,0,\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...),(\eta_1,\eta_2,\eta_3,\eta_4,...)\rangle$

Now,

$\langle T^*(\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...),(\eta_1,\eta_2,\eta_3,\eta_4,...)\rangle$

=$\langle (\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...),T(\eta_1,\eta_2,\eta_3,\eta_4,...)\rangle$

=$\langle(\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...),(0,0,\eta_1,\eta_2,\eta_3,\eta_4,...)\rangle$

Since,$\langle(0,0,\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...),(\eta_1,\eta_2,\eta_3,\eta_4,...)\rangle\neq \langle(\xi_1,\xi_2,\xi_3,\xi_4,\xi_5,...),(0,0,\eta_1,\eta_2,\eta_3,\eta_4,...)\rangle$

So,$T\neq T^* \implies T$ is not Self Adjoint.

Please Check the above proof whether it is correct or not?

I'm not getting how to show that $T$ is bounded...I've given a lots of time in proving the boundedness...If possible,please show how $T$ is bounded?
