Disk algebra is a concept that arises in the area of functional analysis, particularly in the study of function spaces and operator theory. Specifically, it refers to the algebra of holomorphic (analytic) functions defined on the open unit disk in the complex plane. The disk algebra, often denoted as \\( A(D) \\), consists of all continuous functions on the closed unit disk that are holomorphic in the interior of the disk.
