An example of self-homeomorphic dendrite not strongly self-homeomorphic
W. J. Charatonik and A. Dilks asked if any self-homeomorphic dendrite is strongly self-homeomorphic. We give a negative answer.

New exotic minimal sets from pseudo-suspensions of Cantor systems
of homeomorphisms of a class of annulus homeomorphisms we describe, Handel–Anosov–Katok (HAK) homeomorphisms, that generalize the homeomorphism first described by Handel. Given a HAK homeomorphism and a <...

THE COMPLEXITY OF HOMEOMORPHISM RELATIONS ON SOME CLASSES OF COMPACTA
We prove that the homeomorphism relation between compact spaces can be continuously reduced to the homeomorphism equivalence relation between absolute retracts, which strengthens and simplifies recent results of Chang and Gao, and C...

Example of a Smooth homeomorphism violating the Luzin N-1 property
This paper discusses some results concerning the validity of the Luzin N and N−1 properties for homeomorphisms. Also, we present a counterexample in the form of a C∞-homeomorphism that violates the N−1 property....

Homeomorphism with zero Jacobian: Sharp integrability of the derivative
We construct a homeomorphism with zero Jacobian almost everywhere while the integrability of the derivative is the best possible.

Approximation of planar Sobolev W-2,W-1 homeomorphisms by piecewise quadratic homeomorphisms and diffeomorphisms
Given a Sobolev homeomorphism f is an element of W-2,W-1 in the plane we find a piecewise quadratic homeomorphism that approximates it up to a set of epsilon measure. We show that this piecewise quadratic map can be approximated by ...

Homeomorphisms of bounded variation
We show that the inverse of a planar homeomorphism of bounded variation is also of bounded variation. In higher dimensions we show that $f^{-1}$ is of bounded variation provided that $fin W^{1,1}(Omega;rn)$ is a homeomorphism with $...
