Query: Contractibility of Maximal Ideal Spaces of Certain Algebras of Almost
  Periodic Functions   We study some topological properties of maximal ideal spaces of certain
algebras of almost periodic functions. Our main result is that such spaces are
contractible. We present certain corollaries of this result.
