On Weakly Almost Periodic Measures
Daniel Lenz, Nicolae Strungaru
We study the diffraction and dynamical properties of translation bounded weakly almost periodic measures. We prove that the dynamical hull of a weakly almost periodic measure is a…
Profinite automata
Eric Rowland, Reem Yassawi
Many sequences of -adic integers project modulo to -automatic sequences for every . Examples include algebraic sequences of integers, which satisfy this proper…
A characterization of -automatic sequences as columns of linear cellular automata
Eric Rowland, Reem Yassawi
We show that a sequence over a finite field of characteristic is -automatic if and only if it occurs as a column of the spacetime diagram, with eventually peri…
On a zero speed sensitive cellular automaton
Xavier Bressaud, Pierre Tisseur
Using an unusual, yet natural invariant measure we show that there exists a sensitive cellular automaton whose perturbations propagate at asymptotically null speed for almost all c…
A family of sand automata
Nicholas Faulkner, Reem Yassawi
We study some dynamical properties of a family of two-dimensional cellular automata: those that arise from an underlying one dimensional sand automaton whose local rule is obtained…
Embedding odometers in cellular automata
Ethan M. Coven, Reem Yassawi
We consider the problem of embedding odometers in one-dimensional cellular automata. We show that (1) every odometer can be be embedded in a gliders with reflecting walls cellular…
