— We define by simple conditions two wide subclasses of the socalled Arnoux-Rauzy systems; the elements of the first one share the property of (measure-theoretic) weak mixing, thus we generalize and… (More)
In the present work, we give some new results for block minimal residual methods when applied to multiple linear systems. Using the Schur complement, we develop new expressions for the approximation… (More)
In this paper, we prove that the circle multiplication associated with the shifted ‘I% bonacci sequence: (2’2)) is associative for all s 2 5. @ 2002 Elsevier Science Ltd. All rights reserved.
In this paper, we study aperiodic and periodic tilings induced by the Rauzy Fractal and its subtiles associated to beta-substitutions related to the polynomial x − ax − bx− 1 for a ≥ b ≥ 1.

We extend the Killeen-Taylor study in  by investigating in different Banach spaces (l(N), c0(N), cc(N)) the point, continuous and residual spectra of stochastic perturbations of the shift operator… (More)
