The main purpose of this paper is to exhibit the cutoff phenomenon, studied by Aldous and Diaconis [AD]. Let $Q^{* k}$ denote a transition kernel after k steps and π be a stationary measure. We have to find a critical value $k_{n}$ for which the total variation norm between $Q^{* k}$ and π stays very close to 1 for $k ≪ k_{n}$ , and falls rapidly to a value close to 0 for $k \geq k_{n}$ with a fall-off phase much shorter than $k_{n}$ . According to the work of Diaconis and Shahshahani [DS], one can naturally conjecture, for a conjugacy class with...

Polynomial identities of nil algebras of bounded index

Lo scopo di questo lavoro è di dare una nuova descrizione del $T$ -ideale generato dalla nil-identità $x^{n} = 0$ come immagine omeomorfa della $n$ -esima potenza tensoriale simmetrica dell'algebra associativa libera $K 〈X〉$ su un campo $K$ di caratteristica $0$ . Come applicazione calcoliamo il carattere delle conseguenze multilineari di grado $\leq n + 2$ dell'identità $x^{n} = 0$ .

Quasigroup automorphisms and symmetric group characters

Brent Kerby, Jonathan D. H. Smith (2010)

Commentationes Mathematicae Universitatis Carolinae

The automorphisms of a quasigroup or Latin square are permutations of the set of entries of the square, and thus belong to conjugacy classes in symmetric groups. These conjugacy classes may be recognized as being annihilated by symmetric group class functions that belong to a $λ$ -ideal of the special $λ$ -ring of symmetric group class functions.
