Let N be an element of L(P4(C)), defined by N(p(z)) = zp'''(z)+p'(z).Show that N is nilpotent and find the Jordan form of N.
Any help is greatly appreciated!
Find the matricial representation of N wrt the basis
of
. From here it follows at once that N is nilpotent, and check that
but
, so that its Jordan Form is...
