To every one-sided one-dimensional cellular automatonF with neighbourhood radiusr we associate its canonical factor defined by considering only the firstr coordinates of all the images of points under the powers ofF. Whenever the cellular automaton is surjective, this factor is a subshift which plays a primary role in its dynamics. In
this article we study the class of positively expansive one-sided cellular automata, i.e. those that are conjugate to their
canonical factors. This class is a natural generalisation of the toggle or permutative cellular automata introduced in [He].
We prove that the canonical factors of positively expansive one-sided cellular automata are mixing subshifts of finite type
that are shift equivalent to full shifts. Moreover, the uniform Bernoulli measure is the unique measure of maximal entropy
forF. Consequently, their natural extensions are Bernoulli. We also describe a family of non-permutative positively expansive
cellular automata.

The Boltzmann equation for an “isolated” gas system is assumed to form a “dynamical system” in a compact subset of the space of continuous distribution functions (existence assumption). Then the asymptotic stability in the sense of Lyapunov of the total Maxwell distribution is investigated (“approach to equilibrium”). Further the influence of persistent perturbations on the stability behaviour of Boltzmann's equation is considered (“structural stability”). 相似文献

This paper is concerned with the numerical treatment of inverse heat conduction problems. In particular, we combine recent
results on the regularization of ill-posed problems by iterated soft shrinkage with adaptive wavelet algorithms for the forward
problem. The analysis is applied to an inverse parabolic problem that stems from the industrial process of melting iron ore
in a steel furnace. Some numerical experiments that confirm the applicability of our approach are presented. 相似文献

In this article we prove that a minimal topological dynamicalsystem (X, T) with bounded topological sequence entropy hasthe following structure.
Here is the maximal equicontinuous factor of (X, T), ' and' are proximal extensions and ' is a finite-to-one equicontinuousextension. In order to prove this result we consider sequenceentropy tuples and give their complete relation with regionallyproximal tuples. 相似文献
