The complexity of homeomorphism relations on some classes of compacta

Paweł Krupski, Benjamin Vejnar

We prove that the homeomorphism relation between compact spaces can be continuously reduced to the homeomorphism equivalence relation between absolute retracts which strengthens an…

Hyperspaces of continua with connected boundaries in $π$ -Euclidean Peano continua

Paweł Krupski

Let $X$ be a nondegenerate Peano unicoherent continuum. The family $C B (X)$ of proper subcontinua of $X$ with connected boundaries is a $G_{δ}$ -subset of the hyperspace $C (X)$ of all…
