Hi,(adsbygoogle = window.adsbygoogle || []).push({});

What's the relationship between the image and kernel of T and the image and kernel of T^{n}? I think we saw in class something along the lines of:

[tex]Ker(T) \subseteq Ker(T^2)[/tex]

[tex]Im(T) \supseteq Im(T^2)[/tex]

My intuition is that this is also correct for any natural n, but is it true and if so how do you prove it, by induction?

Thanks,

Chen
