</span><b><span lang="EN-US">Full overlaps in mixing Markov Chains</span></b><b><span style="font-size:12pt;line-height:115%" lang="EN-US"><span></span></span></b></p>
<p class="MsoNormal" style="line-height:115%;font-size:11pt;font-family:"Calibri","sans-serif""><span style="font-size:12pt;line-height:115%" lang="EN-US">Abstract: </span><span lang="EN-US">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.<span></span></span></p>
<p class="MsoNormal" style="line-height:115%;font-size:11pt;font-family:"Calibri","sans-serif""><span style="font-size:12pt;line-height:115%" lang="EN-US">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).<span></span></span></p>
