โฆ Synopsis
The purpose of this short note is to show that the set of hereditarily decomposable subcontinua of I n (2 n ฯ) is a coanalytic and non-Borel subset of C(I n ), the space of all subcontinua of I n endowed with the Hausdorff metric. As a simple corollary to this result, we obtain that there is no model for A(I n ), the set of arcwise connected continua in I n .

In this paper we introduce the notion of property of Kelley hereditarily. Among other results we prove that a continuum X is hereditarily locally connected if and only if X has the property of Kelley hereditarily and X is arcwise connected. This is a generalization of a theorem due to Czuba.
The quotients Y = X/conj by the complex conjugation conj : X -+ X for complex rational and Enriques surfaces X defined over Iw are shown to be diffeomorphic to connected sums of D2, whenever the Y are simply connected. 0 1997 Elsevier Science B.V.
