摘要：

We consider the homeomorphic classification of finite-dimensional continua as well as several related equivalence relations. We show that, when n >= 2, the classification problem of n-dimensional continua is strictly more complex than the isomorphism problem of countable graphs. We also obtain results that compare the relative complexity of various equivalence relations. (C) 2019 Elsevier B.V. All rights reserved.
