This description may lead to a sort of computational shape theory. Then we introduce the notion of core for inverse sequences of finite spaces and prove some properties.engjournal articleopen access515.1515.12Algebraic topologyFinite topological spacePosetsShape theoryMatemáticas (Matemáticas)Topología12 Matemáticas1210 Topología
