Disk algebra
In function theory, the disk algebra is the set of continuous functions
- f : D → C,
where D is the closed unit disk in the complex plane C, such that the restriction of f to the interior of D is an analytic function. This set is an algebra over C, since if f and g belong to the disk algebra then so does fg.
It is a subalgebra of the Hardy space H∞.
