[ABE-L] Seminário (online) de Probabilidade - IM-UFRJ - 22/02

[Maria Eulalia Vares]

*Probability Webinar -   IM-UFRJ *



Dear colleagues,

Our next online seminar will be held on Monday, *February 22*, from *3 p.m.
to 4 p.m*. (Rio de Janeiro local time)

The GoogleMeet link for the seminar is  https://meet.google.com/uew-ehhn-kby




Speaker:   *Rodrigo Lambert  (UFU) *

Title: *Full overlaps in mixing Markov Chains*

Abstract: For a string of length n, the overlapping function defines the
greatest size of a repetition, in the sense that it is k if its first and
last k symbols coincide. When the source that generates the strings
satisfies the complete grammar condition, the overlapping function is
always non-negative.

In the present work we deal with the case where the complete grammar
condition is removed, and therefore “negative overlaps” are allowed. We
state a weak convergence theorem when the source is a beta-mixing Markov
Chain with finite diameter (greatest “distance” between two symbols of the
alphabet). This is a work in progress in collaboration with Erika Alejandra
Rada-Mora (UFABC).



All the talks are held in English.

The videos of the online seminars held in 2020 are available at
