On Periodic Sequences for Algebraic Numbers

open access: yesJournal of Number Theory, 2001
For each positive integer n greater than or equal to 2, a new approach to expressing real numbers as sequences of nonnegative integers is given. The n=2 case is equivalent to the standard continued fraction algorithm. For n=3, it reduces to a new iteration of the triangle.

A general framework for the polynomiality property of the structure coefficients of double-class algebras

open access: yes, 2015
Take a sequence of couples $(G_n,K_n)_n$, where $G_n$ is a group and $K_n$ is a sub-group of $G_n.$ Under some conditions, we are able to give a formula that shows the form of the structure coefficients that appear in the product of double-classes of ...

Exact sequences in algebraic $K$-theory

open access: yesIllinois Journal of Mathematics, 1987
Suppose P and M are exact categories (in the sense of Quillen), and that \(F: P\to M\) is an exact functor. If a certain ``cofinality''-type criterion is satisfied by F, it follows that a particular square of spaces is homotopy-Cartesian, giving rise to a long exact sequence of algebraic K-groups which includes the induced maps \(K_ iP\to K_ iM.\) It ...

SL$_{4}(\textbf{Z})$ is not purely matricial field

open access: yesComptes Rendus. Mathématique
We prove that every non-zero finite dimensional unitary representation of $\mathrm{SL}_{4}(\mathbf{Z})$ contains a non-zero $\mathrm{SL}_{2}(\mathbf{Z})$-invariant vector.

Weighted Sequence Spaces and Cyclicity

open access: yesJournal of Mathematical Extension, 2006
In this paper we investigate the cyclicity of the multiplication operator Mz acting on the weighted Hardy spaces of formal Laurent series. AMS Subject Classification: Primary 47B37; Secondary 47A16.

The Iterated Logarithmic Algebra. II. Sheffer sequences

open access: yesJournal of Mathematical Analysis and Applications, 1991
An extension of the theory of the Iterated Logarithmic Algebra gives the logarithmic analog of a Sheffer or Appell sequence of polynomials. This leads to several examples including Stirling's formula and a logarithmic version of the Euler-MacLaurin summation formula.

Resolutions of Cohomology Algebras and other Struggles with Integer Coefficients

open access: yesExtracta Mathematicae, 2017
There is a well known homotopy Π-algebra resolution of a space by wedges of spheres. An attempt to construct the Eckmann-Hilton dual gives a nice resolution for Fp coefficients which can then be used in a spectral sequence.

Fractal algebras of discretization sequences

open access: yes, 2011
These are the lecture notes for a course at the Summer School on "Applied Analysis" at the Technical University Chemnitz in September 2011. We start with the definition of a fractal algebra and show that the fractal property is enormously useful for several spectral approximation problems, e.g. for the convergence of spectra.
