In a recent paper [1]*) of the present author, some results have been established concerning the relations between the inductive (Menger-Urysohn) dimension of a compact (= bicompact) space P and certain properties of the ring C(P) consisting of all (bounded) continuous realvalued functions on P. In the present note I intend to give a characteri zation of the Lebesgue dimension (in a sense slightly different, for non-normal spaces, from the usual one) in terms of the ring C(P), namely, to show that the ...

Nearly discrete and nearly (R) discrete spaces investigated in this note are, roughly speaking, Hausdorff (respectively, regular) spaces the topology of which cannot be modified without either some open set becoming non-open or some non-isolated point becoming isolated.It is immediately seen that discrete (i.e. Buch that every subset is open) spaces as well as spaces investigated by E. HEWITT [1] *) and by the present author [2] and called maximal (maximal completely regular) in [1], minimal (JK-minimal) in [ ...
