A discrete-time retarder is a stochastic increasing function , whose distribution is invariant by conjugation by the translations of Z. Continuous-time retarders can be defined similarly.About these objects, which can be composed, we prove theorems of two kinds. First, we establish various inequalities about the composition and iteration of retarders whose delay is (p−1)-integrable. Then we prove a super-multiplicative ergodic theorem, which can be used to define the “cycle time” of a retarder. 相似文献

The purpose of this paper is to give a necessary and sufficient condition for an idempotent semigroup with identity element
to be linearly orderable.

Cet article regroupe queiques remarques sur les relations d'inclusion entre aretes et ensembles le sommets dans un hypergraphe et sur la classe des hypergraphes H dont les stables maximaux sont les transversaux minimaux de Hc, hypergraphe des complémentaires des arêtes de H. Les hypergraphes uniformes (en particulier les graphes), duaux de graphes et hypergraphes conformes ayant cette propriéte sont caractérisés. 相似文献

A necessary and sufficient condition is given in order that a lattice-ordered semigroup admit a totally ordered ?-homomorphic image (Theorem 1). This permits us to give (Theorem 2) a necessary and sufficient condition that a lattice-ordered semigroup be representable, that is, that it be ?-isomorphic to a subdirect product of totally ordered semigroups, thereby solving a problem posed by L. Fuchs ([2], p. 289). We also establish a necessary and sufficient condition that a semigroup be an o-semigroup, that is, that it admit a structure of totally ordered semigroup (Theorem 3). 相似文献

We show here that row-reducing a quantum matrix produces another quantum matrix satisfying the same relations as those of the original quantum matrix ring Mq(n). As a corollary, the image of the quantum determinant in the abelianization of the total ring of quotients of Mq(n ), equals the Dieudonné determinant of the quantum matrix. 相似文献
