Re: Question in the analysis

This is pretty easy. For i), there is no function S, whether linear or not, such that ST = id.

Re: Question in the analysis

Notice that once you have taken $T(\lambda_1, \lambda_2, \lambda_3, \cdot\cdot\cdot)= (\lambda_2, \lambda_3, \lambda_4, \cdot\cdot\cdot)$ you have lost all information on $\lambda_1$ . There is no way to know what $\lambda_1$ is in order to regain it. A more technical way of saying that is that T is not "one to one". Many different vectors $(\lambda_1, \lambda_2, \lambda_3, \cdot\cdot\cdot)$ will be mapped into the same $(\lambda_2, \lambda_3, \lambda_4, \cdot\cdot\cdot)$ .

As for the second problem, the only difficulty is that there are an infinite number of correct answer- just choose one.
