Abstract
For an exotic locally compact Hausdorff space L, constructed under the assumption of Ostaszewski’s \(\clubsuit \)-principle, and a countable ordinal space \(\alpha \), we prove that all operators defined on \(C_0(\alpha \times L)\) have the simplest possible form. We also investigate the geometry of such space \(C_0(\alpha \times L)\) and we classify up to isomorphisms all its complemented subspaces.
