Nov 3, 2020 at 11:51 | comment | added | Ruy | This is Proposition 2.5 in Lance's book, but it takes a bit of interpretation. You need to take the Hilbert module $E$ mentioned there to be $E=B$, and then you need to know that $\mathcal L(E)$ is the multiplier algebra of $B$ (actually this is Lance's definition of the multiplier algebra). | |

Nov 3, 2020 at 2:25 | comment | added | Ruy | There is a general result that says that you get your extension provided your morphism $\phi:A\to B$ satisfies $\overline{\phi(A)B}=B$. Since this holds in your case, your extension exists. | |
