Approximation of Volume-preserving Homeomorphisms by Volume-preserving Diffeomorphisms
Given a volume-preserving homeomorphism of a smooth manifold of dimension n ≥ 5, we give a necessary and sufficient condition for uniform approximability by (volume-preserving) diffeomorphisms.
متن کاملMeasure Preserving Homeomorphisms at Fixed Points
In an article of a few years ago [2] Kerékjartó obtained interesting results about certain types of transformations which he called similitudes. With a few modifications and extensions his methods can be used to gain information about the structure of measure preserving transformations at fixed points. For simplicity the results are formulated for Euclidean w-space although they could easily be...
متن کاملOn Fiber-preserving Isotopies of Surface Homeomorphisms
We show that there are homeomorphisms of closed oriented genus g surfaces Σg which are fiber-preserving with respect to an irregular branched covering Σg → S2 and isotopic to the identity, but which are not fiber-isotopic to the identity.

متن کاملPeriodic, Locally Linear, and Chaotic Approximations to Volume Preserving Homeomorphisms
We modify a combinatorial idea of Peter Lax, to uniformly approximate any volume preserving homeomorphism h of the closed unit cube In; n 2; by another one ĥ such that either: (i) ĥ rigidly permutes an in nite family of dyadic cubes of total volume one, or (ii) ĥ is chaotic in the sense of Devaney. The rst result (i) generalizes a similar result of Oxtoby and Ulam, yielding an approximation whi...
