Unit Elements in the Double Dual of a Subalgebra of the Fourier Algebra A(G)
Abstract. Let ๐ be a Banach algebra with a bounded right approximate identity and let โฌ be a closed ideal of ๐. We study the relationship between the right identities of the double duals โฌ** and ๐** under the Arens product. We show that every right identity of โฌ** can โฆ
