Abstract:
Given a branching random walk on a set $X$, we study its extinction probability vectors $mathbf{q}(cdot,A)$. Their components are the probability that the process goes extinct in a fixed $Asubseteq X$, when starting from a vertex $xin X$. The set of extinction probability vectors (obtained letting $A$ vary among all subsets of $X$) is a subset of the set of the fixed points of the generating function of the branching random walk. In particular here we are interested in the cardinality of the set of extinction probability vectors. We prove results which allow to understand whether the probability of extinction in a set $A$ is different from the one of extinction in another set $B$. In many cases there are only two possible extinction probability vectors and so far, in more complicated examples, only a finite number of distinct extinction probability vectors had been explicitly found. Whether a branching random walk could have an infinite number of distinct extinction probability vectors was not known. We apply our results to construct examples of branching random walks with uncountably many distinct extinction probability vectors.

Abstract:
While derivations of the characterization of the $d$-variate exchangeable Marshall–Olkin copula via $d$-monotone sequences relying on basic knowledge in probability theory exist in the literature, they contain a myriad of unnecessary relatively complicated computations. We revisit this issue and provide proofs where all undesired artefacts are removed, thereby exposing the simplicity of the characterization. In particular, we give an insightful analytical derivation of the monotonicity conditions based on the monotonicity properties of the survival probabilities.

Abstract:
We consider a random object that is associated with both random walks and random media, specifically, the superposition of a configuration of subcritical Bernoulli percolation on an infinite connected graph and the trace of the simple random walk on the same graph. We investigate asymptotics for the number of vertices of the enlargement of the trace of the walk until a fixed time, when the time tends to infinity. This process is more highly self-interacting than the range of random walk, which yields difficulties. We show a law of large numbers on vertex-transitive transient graphs. We compare the process on a vertex-transitive graph with the process on a finitely modified graph of the original vertex-transitive graph and show their behaviors are similar. We show that the process fluctuates almost surely on a certain non-vertex-transitive graph. On the two-dimensional integer lattice, by investigating the size of the boundary of the trace, we give an estimate for variances of the process implying a law of large numbers. We give an example of a graph with unbounded degrees on which the process behaves in a singular manner. As by-products, some results for the range and the boundary, which will be of independent interest, are obtained.

Abstract:
Consider a supercritical branching random walk on the real line. The consistent maximal displacement is the smallest of the distances between the trajectories followed by individuals at the $n$th generation and the boundary of the process. Fang and Zeitouni, and Faraud, Hu and Shi proved that under some integrability conditions, the consistent maximal displacement grows almost surely at rate $lambda^{*}n^{1/3}$ for some explicit constant $lambda^{*}$. We obtain here a necessary and sufficient condition for this asymptotic behaviour to hold.

This paper studies a service system in which arriving customers are provided with information about the delay they will experience. Based on this information they decide to wait for service or to leave the system. The main objective is to estimate the customers' patience-level distribution and the corresponding potential arrival rate, using knowledge of the actual workload process only. We cast the system as a queueing model, so as to evaluate the corresponding likelihood function. Estimating the unknown parameters relying on a maximum likelihood procedure, we prove strong consistency and derive the asymptotic distribution of the estimation error. Several applications and extensions of the method are discussed. In particular, we indicate how our method generalizes to a multi-server setting. The performance of our approach is assessed through a series of numerical experiments. By fitting parameters of hyperexponential and generalized-hyperexponential distributions our method provides a robust estimation framework for any continuous patience-level distribution.

Abstract:
The recurrence and transience of persistent random walks built from variable length Markov chains are investigated. It turns out that these stochastic processes can be seen as Lévy walks for which the persistence times depend on some internal Markov chain: they admit Markov random walk skeletons. A recurrence versus transience dichotomy is highlighted. Assuming the positive recurrence of the driving chain, a sufficient Fourier criterion for the recurrence, close to the usual Chung–Fuchs one, is given and a series criterion is derived. The key tool is the Nagaev–Guivarc’h method. Finally, we focus on particular two-dimensional persistent random walks, including directionally reinforced random walks, for which necessary and sufficient Fourier and series criteria are obtained. Inspired by ( Adv. Math. 208 (2007) 680–698), we produce a genuine counterexample to the conjecture of ( Adv. Math. 117 (1996) 239–252). As for the one-dimensional case studied in ( J. Theoret. Probab. 31 (2018) 232–243), it is easier for a persistent random walk than its skeleton to be recurrent. However, such examples are much more difficult to exhibit in the higher dimensional context. These results are based on a surprisingly novel – to our knowledge – upper bound for the Lévy concentration function associated with symmetric distributions.

Can young people be united in faith, irrespective of their ethnic background? The answer is yes!

Denver Newsroom, May 7, 2020 / 06:01 pm (CNA).- A young Catholic artist has drawn an image of the Blessed Virgin Mary on her parents' driveway bringing religious art to her local community during the quarantine.

The Diocese of Fargo posted on Facebook May 4 an image of Our Lady of Lourdes drawn by Maria Loh, a 17-year old who grew up in Fargo. She said it was an enjoyable experience to share her faith and art with her neighborhood.

“Being able to interact with people when they walked by was very moving in a way because a lot of people have never really seen sidewalk art done like that locally. So being able to share in that kind of experience, it was very, very good,” she told CNA.

Loh has recently been inspired by chalk art and pastels, which, she said, have vibrant and beautiful colors. She has drawn on the sidewalks a few times, including two images of Mary - Madonna of the Lillies and the Pieta by William Adolphe-Bouguereau.

Her most recent chalk drawing was Our Lady of Lourdes by Hector Garrido - an image she had seen as a magnet on her grandparents' refrigerator growing up. The picture has always been an inspiration, she said, noting that she decided to replicate it after Our Lady of Lourdes Shrine in France had temporarily closed due to the coronavirus pandemic.

“I heard that the shrine had been temporarily closed off to the public, and I remember … thinking that's really sad because especially in this time, we’re really looking for healing in more ways than one, like physically and mentally and spiritually,” she said.

“It really felt like people wouldn't be able to go to experience that. So I felt like drawing this image of Our Lady of Lourdes would be a good way to remind people that Our Lady is still with us even if we can’t go to her shrine.”

Loh, the oldest of five, has been involved with art projects and drawing for her entire life. She said, growing up in a Catholic family, she has been inspired by her faith and the religious art in churches.

“I see our faith as so precious... Especially in the form of the Eucharist - the actual body and blood of Christ, I've seen that we are very blessed to have that in our faith. It's something that has impacted a lot of my life growing up,” she said.

While she was working on the piece, Loh said, a majority of passersby did not know who the lady in the image was. She expressed hope that the picture would help remind people of Mary and the beauty of the Church, which, she said, is a powerful attraction to the faith.

“One thing that I hope this kind of art and image will evoke is a desire to come to know who Mary is and how rich our faith is. … All the beautiful art that can be seen in Catholic churches, especially like in Rome, there's almost a transcendental beauty to them that draws people into the faith to come to know things that they've never dreamed of before,” she said.

As Loh finishes her junior year of high school, she expressed the possibility of art school after graduation, but, while she is still uncertain of the future, said art will not be dropped anytime soon.

“I can definitely see [art school] being a possibility. I’ll have to spend some time, especially with God trying to figure out what he wants me to do. But, I don't think art is going out of my life anytime soon,” she said.
