Abstract

Nogura showed that whereas Arhangel'skiǐ's properties α₁, α₂ and α₃ are preserved by finite products, the property α₄ is not. It is shown here that for each space X the properties α₂, α₃ and α₄, are the same for the function space C_p(X). As a consequence, α₄ is closed under finite products of such function spaces.
