ON MÖBIUS DISJOINTNESS FOR INFINITE MEASURE-PRESERVING TRANSFORMATIONS

open access: yesKyushu Journal of Mathematics
The property of `Möbius disjointess', asymptotic orthogonality of the classical Möbius function to an observable on a topological dynamical system, is studied in the setting of infinite measure-preserving systems. Disjointness is shown to not hold at almost all points in the class of continuous bounded integrable observables for an ergodic system, and ...

Semigroups of order-decreasing transformations [PDF]

open access: yes, 2012
Let X be a totally ordered set and consider the semigroups of orderdecreasing (increasing) full (partial, partial one-to-one) transformations of X. In this Thesis the study of order-increasing full (partial, partial one-to-one) transformations has been

Properties of measures supported on fat Sierpinski carpets [PDF]

open access: yes, 2006
In this paper we study certain conformal iterated function schemes in two dimensions that are natural generalizations of the Sierpinski carpet construction. In particular, we consider scaling factors for which the open set condition fails.

On Partially Trace Distance Preserving Maps and Reversible Quantum Channels

open access: yesJournal of Applied Mathematics, 2013
We give a characterization of trace-preserving and positive linear maps preserving trace distance partially, that is, preservers of trace distance of quantum states or pure states rather than all matrices.

Bidirectional Model Transformations in QVT: Semantic Issues and Open Questions [PDF]

open access: yes, 2007
We consider the OMG's Queries, Views and Transformations (QVT) standard as applied to the specification of bidirectional transformations between models. We discuss what is meant by bidirectional transformations, and the model-driven development scenarios

Generic behavior of a measure-preserving transformation [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2018
Del Junco–Lemańczyk [Generic spectral properties of measure-preserving maps and applications. Proc. Amer. Math. Soc., 115 (3) (1992)] showed that a generic measure-preserving transformation satisfies certain orthogonality conditions. More precisely, there is a dense $G_{\unicode[STIX]{x1D6FF}}$ subset of measure preserving transformations such that ...

Amenability, Countable Equivalence Relations, and Their Full Groups [PDF]

open access: yes, 2008
This thesis consists of an introduction and four independent chapters. In Chapter 1, we study homeomorphism groups of metrizable compactifications of the natural numbers. Those groups can be represented as almost zero-dimensional Polishable subgroups

Unique normal forms near a degenerate elliptic fixed point in two-parametric families of area-preserving maps [PDF]

open access: yes, 2014
We derive simplified normal forms for an area-preserving map in a neighbourhood of a degenerate resonant elliptic fixed point. Such fixed points appear in generic families of area-preserving maps. We also derive a simplified normal form for a generic two-

Infinite Dimensional Maximal Torus Revisited

open access: yesMathematics
Let Tm be the maximal torus of a set of m×m unitary diagonal matrices. Let T be a collection of all maps that rigidly rotate every circle of latitude of the sphere with a fixed angle.
