On complemented subspace of convergence-free spaces
Abstract
The author proved in 1935 (Math. Annalen 111,229-258) that two convergence-free spaces 
and 
, of countable degree are isomorphic if and only if there exists a perturbation of the coordinates which transforms , into. The author gives a ne w exposition of this result and its consequences and formulates some unsolved problems on the structure of the complemented subspaces of spaces of countable degree.
