Abstract

The deck of a topological space XX is the set D(X)={[X{x}] ⁣:xX}\mathcal{D}(X)=\{[X \setminus \{x\}] \colon x \in X\}, where [Z][Z] denotes the homeomorphism class of ZZ. A space XX is topologically reconstructible if whenever D(X)=D(Y)\mathcal{D}(X)=\mathcal{D}(Y) then XX is homeomorphic to YY. It is shown that all metrizable compact connected spaces are reconstructible. It follows that all finite graphs, when viewed as a 1-dimensional cell-complex, are reconstructible in the topological sense, and more generally, that all compact graph-like spaces are reconstructible.
