Proof that for a strongly continuous contraction resolvent, there is exactly one linear operator that...

I have questions about the proof of the following Proposition from the book Introduction to the Theory of Non-Symmetric Dirichlet forms.



enter image description here



First, how do we get the independence of $G_alpha (B)$ of $alpha$ by 1.4(iii) and that each $G_alpha$ is one-to-one by 1.4(i) and 1.4(iii)?



Second, once we conclude that $alpha - G_alpha^{-1} = beta - G_beta^{-1}$, how do we get that $D(L)=G_alpha (B)$ is dense in $B$ by 1.4 (i)?



I would greatly appreciate any help.
