SIFAT ALJABAR BANACH KOMUTATIF DAN ELEMEN IDENTITAS PADA KELAS D(K)

ABSTRACT: The first Baire class of bounded functions on separable metric spaces K denoted by B1(k). One of the most important subclass of B1(k) is D(K), by D(K) is denoted the class of all functions on K which are differences of bounded semicontinuous functions. In this paper we proved that D(K) is abelian Banach algebra and identity element
