Branching processes: their role in epidemiology. [PDF]
Int J Environ Res Public Health, 2010 Branching processes are stochastic individual-based processes leading consequently to a bottom-up approach. In addition, since the state variables are random integer variables (representing population sizes), the extinction occurs at random finite time on the extinction set, thus leading to fine and realistic predictions. Starting from the simplest and

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2021 В данной работе рассматриваются ветвящиеся случайные процессы с дискретным временем в двух предположениях: в начальный момент времени имеется одна частица или в начальный момент времени существует большое число частиц.

Immortal branching processes [PDF]
Physica A: Statistical Mechanics and its Applications, 2021 We introduce and study the dynamics of an \emph{immortal} critical branching process. In the classic, critical branching process, particles give birth to a single offspring or die at the same rates. Even though the average population is constant in time, the ultimate fate of the population is extinction.

Demographic Dynamics in Multitype Populations with Migrations
Mathematics, 2021 This research work deals with mathematical modeling in complex biological systems in which several types of individuals coexist in various populations. Migratory phenomena among the populations are allowed.

Geometric branching reproduction Markov processes
Modern Stochastics: Theory and Applications, 2020 We present a model of a continuous-time Markov branching process with the infinitesimal generating function defined by the geometric probability distribution.

Numerical solutions to Giovannini’s QCD parton branching processes [PDF]
EPJ Web of Conferences, 2020 In 1979, Giovannini [1] formulated multiparticle production as a manifestation of four QCD processes: A: g → gg (gluon bremsstrahlung), A-: q → qg (quark bremsstrahlung), B: g → qq (quark pair creation) and C: g → ggg (four-gluon vertex).

Modeling Y-Linked Pedigrees through Branching Processes
Mathematics, 2020 A multidimensional two-sex branching process is introduced to model the evolution of a pedigree originating from the mutation of an allele of a Y-linked gene in a monogamous population. The study of the extinction of the mutant allele and the analysis of

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