The Complexity of the Classification Problems of Finite-Dimensional Continua
Cheng Chang, Su Gao
We consider the homeomorphic classification of finite-dimensional continua as well as several related equivalence relations. We show that, when , the classification probl…

The complexity of the classification problem of continua
Cheng Chang, Su Gao
We prove that the homeomorphism problem for connected compact metric spaces is Borel bireducible with a universal orbit equivalence relation induced by a Borel action of a Polish g…
