Abstract: For every we construct an -dimensional compact subset of some Euclidean space so that none of the canonical projections of on its two-dimensional coordinate subspaces has a stable value when restricted to . This refutes a longstanding claim due to Chogoshvili. To obtain this we study the lattice of upper semicontinuous decompositions of and in particular its sublattice that consists of monotone decompositions when is hereditarily indecomposable.
