On a metric space $X$, Did said:
the space $M_1$ of probability measures is included in the dual of the space $C_b$ of bounded continuous functions.
I was wondering what is the representation theorem for the dual of $C_b(X)$, which is supposed to have $M_1$ as its subset?
I saw in Wikipedia, only Riesz representation theorems for $C_0$ and $C_c$, not for $C_b$.
Thanks and regards!
