โฆ Synopsis
We investigate continua with the property that the cone ojGrer* the continuum is homeomorphic to the hyperspace of subcontinua of the cantMum. Among our results ale the following theorems: (i) Such a finite-dimensional continuum must be airiodic and onedimensional; (ii) if such a continuum is heredit-tily decomposable, then it mus: be an arc, an arl:wiseconnected circie-iike continuum, or a compactification of either [&I) or R with remainder ei,her a circle or an arc. Examples are given to show that noxne of these poAGlities may the omit ted.
