The object of study of this work is the invariant characteristics of filtrations in discrete, negative time, pioneered by Vershik. We prove the equivalence between I-cosiness and standardness without using Vershik’s standardness criterion. The equivalence between I-cosiness and productness for homogeneous filtrations is further investigated by showing that the I-cosiness criterion is equivalent to Vershik’s first level criterion separately for each random variable. We also aim to derive the… 
On Vershikian and I-Cosy Random Variables and Filtrations
We prove that the equivalence between Vershik's standardness criterion and the I-cosiness criterion for a filtration in discrete, negative time holds separately for each random variable. This gives a
Vershik’s Intermediate Level Standardness Criterion and the Scale of an Automorphism
In the case of r n -adic filtrations, Vershik’s standardness criterion takes a particular form, hereafter called Vershik’s intermediate level criterion. This criterion, whose nature is combinatorial,

TLDR
Among the main results, it is proved that the scaled entropy of the filtration generated by the Vershik progressive predictions of a random variable is equal to the scaling entropy of this random variable.
The filtration of the split-words process
Smorodinsky and Laurent have initiated the study of the filtrations of split-word processes, in the framework of discrete negative time. For these filtrations, we show that Laurent’s sufficient
Filtrations at the threshold of standardness
A. Vershik discovered that filtrations indexed by the non-positive integers may have a paradoxical asymptotic behaviour near the time $$-\infty $$, called non-standardness. For example, two dyadic
Filtrations of the Erased-Word Processes
TLDR
It is shown that the poly-adic filtration generated by such a process is standard and constructed with the help of Vershik's theory of filtrations in discrete negative time.

Cramér-Hida Representations from “First Principles”
The Cramer-Hida representation shall be, at first, the decomposition of a function, with values in a Hilbert space, into manageable parts, one continuous, and one discontinuous. The continuous part
The theory of filtrations of subalgebras, standardness, and independence
The survey is devoted to the combinatorial and metric theory of filtrations, i.\,e., decreasing sequences of $\sigma$-algebras in measure spaces or decreasing sequences of subalgebras of certain
Complementability and Maximality in Different Contexts: Ergodic Theory, Brownian and Poly-Adic Filtrations
The notions of complementability and maximality were introduced in 1974 by Ornstein and Weiss in the context of the automorphisms of a probability space, in 2008 by Brossard and Leuridan in the

On Vershik’s Standardness Criterion and Tsirelson’s Notion of Cosiness
Building on work done by A. Vershik some thirty years ago, the insight into different types of filtrations has recently seen important progress, due in particular to B. Tsirelson, and L. Dubins, J.
Bernoullis are standard when entropy is not an obstruction
AbstractIn this paper we look atr equivalence, which is an equivalence relation that is implicit in Vershik's classification ofr-adic decreasing sequences of σ-algebras, and also in work of Stepin.
Old and New Tools in the Theory of Filtrations
Vershik’s theory of standard filtered probability spaces and standardness criterion (established in the early seventies) are presented to a non-specialized audience and illustrated with examples.
Addendum to our paper ‘Decreasing sequences of sigma fields: product type, standard, and substandard’
In a note which we received from W. Schachermayer he called attention to some confusion in his paper [S1], which he said was noticed by H. Buhler. Our reading of this note made us unhappily aware
