On the profile of trees with a given degree sequence

Osvaldo Angtuncio, Gerónimo Uribe Bravo

A degree sequence is a sequence $s = (N_{i}, i \geq 0)$ of non-negative integers satisfying $1 + \sum_{i} i N_{i} = \sum_{i} N_{i} < \infty$ . We are interested in the uniform distribution $\mathb…

$ε$ -strong simulation of the convex minorants of stable processes and meanders

Jorge Ignacio González Cázares, Aleksandar Mijatović, Gerónimo Uribe Bravo

Using marked Dirichlet processes we characterise the law of the convex minorant of the meander for a certain class of Lévy processes, which includes subordinated stable and symmetr…

Invariance principles for local times in regenerative settings

Aleksandar Mijatović, Gerónimo Uribe Bravo

Consider a stochastic process $X$ , regenerative at a state $x$ which is instantaneous and regular. Let $L$ be a regenerative local time for $X$ at $x$ . Suppos…

Dini derivatives for Exchangeable Increment processes and applications

Osvaldo Angtuncio Hernández, Gerónimo Uribe Bravo

Let $X$ be an exchangeable increment (EI) process whose sample paths are of infinite variation. We prove that, for any fixed $t$ almost surely, \[ \limsup_{h\to 0 \pm} (X_{t+h}-X_t…

Random walks with preferential relocations and fading memory: a study through random recursive trees

Cécile Mailler, Gerónimo Uribe Bravo

Consider a stochastic process that behaves as a $d$ -dimensional simple and symmetric random walk, except that, with a certain fixed probability, at each step, it chooses instead to…
