 Title: Complexity of the homeomorphism relation between compact spaces

 Abstract  

 We study the complexity of the homeomorphism relation of compact metrizable spaces when restricted to some subclasses such as continua, absolute retracts, regular continua or regular compacta. The complexity of an equivalence relation on a Polish space is compared with some others (e.g. with the universal orbit equivalence relation) using the notion of Borel reducibility.
