A pro-2 group with full normal Hausdorff spectra

نویسندگان

چکیده

Abstract We construct a 2-generated pro-2 group with full normal Hausdorff spectrum [ 0 , 1 stretchy="false">] [0,1] , respect to each of the four standard filtration series: 2-power series, lower 2-series, Frattini and dimension subgroup series. This answers question Klopsch second author, for even prime case; odd case was settled by first author Klopsch. Also, our construction gives example finitely generated 2-series.

Dimensional Hausdorff properties of singular continuous spectra.

We present an extension of the Gilbert-Pearson theory of subordinacy, which relates dimensional Hausdorff spectral properties of one-dimensional Schrödinger operators to the behavior of solutions of the corresponding Schrödinger equation. We use this theory to analyze these properties for several examples having the singular-continuous spectrum, including sparse barrier potentials, the almost M...

Invariant Sets with Zero Measure and Full Hausdorff Dimension

For a subshift of finite type and a fixed Hölder continuous function, the zero measure invariant set of points where the Birkhoff averages do not exist is either empty or carries full Hausdorff dimension. Similar statements hold for conformal repellers and two-dimensional horseshoes, and the set of points where the pointwise dimensions, local entropies, Lyapunov exponents, and Birkhoff averages...

Duality and Pro - Spectra

Cofiltered diagrams of spectra, also called pro-spectra, have arisen in diverse areas, and to date have been treated in an ad hoc manner. The purpose of this paper is to systematically develop a homotopy theory of pro-spectra and to study its relation to the usual homotopy theory of spectra, as a foundation for future applications. The surprising result we find is that our homotopy theory of pr...

Generalized Cohomology of Pro-spectra

We present a closed model structure for the category of pro-spectra in which the weak equivalences are detected by stable homotopy pro-groups. With some bounded-below assumptions, weak equivalences are also detected by cohomology as in the classical Whitehead theorem for spectra. We establish an Atiyah-Hirzebruch spectral sequence in this context, which makes possible the computation of topolog...
