$L^p$-Spaces as Quasi *-Algebras

The Banach space $L^p(X,\mu )$, for $X$ a compact Hausdorff measure space, is considered as a special kind of quasi -algebra (called CQ-algebra) over the C*-algebra $C(X)$ of continuous functions on $X$. It is shown that, for $p \geq 2$,$(L^p(X,\mu), C(X))$ is *-semisimple (in a generalized sense). Some consequences of this fact are derived.
