My answer is this:

Consider the following linear map:

T|u>=|u> if |u> belongs to V-U and T|u>=|0> if |u> belongs to U

Therefore kerT=U

Is this correct?

nooo …

i] that's a map from V to V, not to W

ii] what do you mean by V-U ? (eg what is R

Silly me, I overlooked it xD

ii] what do you mean by V-U ? (eg what is R^{3}- R^{2}?)

I mean the elements of V that do not belong in U.

Well, the correct answer would be: ℝ^3-ℝ^2={(0,0,z):z is real

that's a line

add a line to R

I think you need to review your definitions!
