Space of continuous functions on a compact space
= Space of continuous functions on a compact space
{title2=$C(K)$}
For a <compact Hausdorff space> $K$, $C(K)$ consists of continuous scalar-valued functions with the <supremum norm>. It is a <Banach space> and, with complex scalars, pointwise multiplication and conjugation make it a commutative unital <C-star algebra>.
