Abstract: | We consider some almost periodic type function algebras on a weighted semitopological semigroup, and using the set of multiplicative
means on each of these algebras, we define their corresponding weighted semigroup compactifications. This will constitute
an effective tool for investigating the properties of the function algebras concerned. We also show that these compactifications
do not retain all the nice properties of the ordinary semigroup compactifications unless we impose some restrictions on the
weight functions. |
