Abstract

In 2014, V. Martínez-de-la-Vega and P. Minc proved that, for an arbitrary nondegenerate metric continuum X  , there is an uncountable collection KK of topologically distinct metric compactifications of [1,∞)[1,∞), having X   as the remainder. It is not clear without the continuum hypothesis that cardinality of KK is 2ℵ02ℵ0. However, the continuum hypothesis is rarely necessary in the theory of metric continua. To support this assertion, presented here is an explicit construction of a compact metric space K   with 2ℵ02ℵ0 mutually not homeomorphic components each of which is a compactification of [1,∞)[1,∞), having a copy of X as the remainder.
