statement of the proof was that $S$ was closed from below, and bounded from below. It is fine when they say that $B$ is bounded below which is also obvious from the definition. So, there should be a g.l.b. for the set $B$, which is denoted by ${b}_{0}$.

Now why there should exist a sequence of points $\left({\mathbf{y}}^{\mathbf{(}\mathbf{n}\mathbf{)}}\right)$ in the risk set $S$ such that $\sum {p}_{j}{y}_{j}\to {b}_{0}$? Is ${b}_{0}$ a limit point of $B$? Is $B$ closed ? Even if this happen why ${b}_{0}$ which is greatest lower bound of $B$ should belong to $B$?

Next, I guess they apply Bolzano Weierstrass theorem to say that ${\mathbf{y}}^{\mathbf{0}}$ is a limit point of the sequence $\left({\mathbf{y}}^{\mathbf{(}\mathbf{n}\mathbf{)}}\right)$. But why the last step $\sum {p}_{j}{y}_{j}^{0}={b}_{0}$?
