Abstract:

For a compact Lie group G , we characterize free G -spaces that admit free G -compactifications. For such G -spaces, a universal compact free G -space of given weight and given dimension is constructed. It is shown that if G is finite, the n -dimensional Menger free G -compactum μ n is universal for all separable, metrizable free G -spaces of dimension less than or equal to n . Some of these results are extended to the case of G -spaces with a single orbit type.
