Cesarruletita Posted November 18, 2012 Share Posted November 18, 2012 (edited) Let [V] a vector space over the field [F] and let [g] the polynomial on [F] given by [g (x) = a_0 + ... + a_nx a_1x + ^ n]. For each operator [T] on [V] defines a transformation [G (t): V -----> V] as [g (t) = a0 I+ a_1T +......+ a_nT ^ n] a) Prove that [g (T)] is an operator on [V] b) Let [a = a_0 + a_1 + ... + a_n] and let [E] a projection of [V]. Prove that if [n] is an even integer if [a = a_0], then [g (E)] is a scalar multiple of the identity operator.

ydoaPs Posted November 19, 2012 Share Posted November 19, 2012 Your relation G(t) is mapping V onto V? Link to comment Share on other sites More sharing options...
