The Diameter of the Minimum Spanning Tree of a Complete Graph [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
Let $X_1,\ldots,X_{n\choose 2}$ be independent identically distributed weights for the edges of $K_n$. If $X_i \neq X_j$ for$ i \neq j$, then there exists a unique minimum weight spanning tree $T$ of $K_n$ with these edge weights.

Branching processes in random environment die slowly [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Let $Z_n,n=0,1,\ldots,$ be a branching process evolving in the random environment generated by a sequence of iid generating functions $f_0(s),f_1(s),\ldots,$ and let $S_0=0$, $S_k=X_1+ \ldots +X_k,k \geq 1$, be the associated random walk with $X_i=\log ...

Timed Branching Processes [PDF]

open access: yes2010 Seventh International Conference on the Quantitative Evaluation of Systems, 2010
We study Timed Branching Processes (TBPs), a natural extension of (multitype) Branching Processes (BPs) where each entity is equipped with a finite set of private continuous variables, called clocks. Clocks grow uniformly with the same rate and using them various timing constraints can be imposed on the branching rules of the system, e.g.

In the Garden of Branching Processes

open access: yesSIAM Review, 2004
The review article summarizes the theory of multitype branching processes in continuous time. The process includes immigration which is modelled as a Poisson stream of immigrant particles. Marked Poisson processes and Campbell's formulae are applied. The extinction probability is calculated.

Critical branching processes in a sparse random environment

open access: yesModern Stochastics: Theory and Applications, 2023
We introduce a branching process in a sparse random environment as an intermediate model between a Galton–Watson process and a branching process in a random environment.

Transposed Branching Processes

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1954
Summary We shall show in this paper how, in studying the growth-rate of a deterministic branching process, a simple change of viewpoint, which is quite trivial theoretically, may nevertheless lead to surprising computational simplifications; and, in the course of this, we shall indicate a basis on which the generated population can ...

Branching Processes - A General Concept

open access: yesLatin American Journal of Probability and Mathematical Statistics, 2021
The paper has four goals. First, we want to generalize the classical concept of the branching property so that it becomes applicable for historical and genealogical processes (using the coding of genealogies by ($V$-marked) ultrametric measure spaces leading to state spaces $\mathbb{U}$ resp. $\mathbb{U}^V$).

The Width of Galton-Watson Trees Conditioned by the Size [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2004
It is proved that the moments of the width of Galton-Watson trees of size n and with offspring variance σ ^2 are asymptotically given by (σ √n)^pm_p where m_p are the moments of the maximum of the local time of a standard scaled Brownian excursion.

Expression and functional analysis of CsA-IPT5 splice variants during shoot branching in Camellia sinensis

open access: yesFrontiers in Plant Science, 2022
Alternative splicing (AS) is a process by which several functional splice variants are generated from the same precursor mRNA. In our recent study, five CsA-IPT5 splice variants with various numbers of ATTTA motifs in the untranslated regions (UTRs) were
