Estimates of the extinction probability of the Galton-Watson process
, 1995 Узагальнено результат Квайна про збіжність до одиниці ймовірності виродження суперкритичного процесу Гальтона-Ватсона, якщо середнє число нащадків наближається до одиниці при відсутності обмежень на факторіальні моменти.We generalize Quine's result on ...

Mathematical modeling of the spread of the coronavirus under strict social restrictions
Mathematical Methods in the Applied Sciences, EarlyView., 2021 We formulate a simple susceptible‐infectious‐recovery (SIR) model to describe the spread of the coronavirus under strict social restrictions. The transmission rate in this model is exponentially decreasing with time. We find a formula for basic reproduction function and estimate the maximum number of daily infected individuals.

On the probability of extinction of a Galton-Watson process
A new lower bound for the probability of extinction of a Galton-Watson process is derived. The result extends the classical extinction probability theorem of J.F.

The probability of containment for multitype branching process models for emerging epidemics
, 2011 This paper is concerned with the definition and calculation of containment probabilities for emerging disease epidemics. A general multitype branching process is used to model an emerging infectious disease in a population of households. It is shown that

Biological Diversity, EarlyView.Density estimates of two endangered rodent subspecies, endemic to Key Largo, Florida, USA. These findings illustrate the contrasting dynamics of two native species associated with the prevalence of invasive Burmese pythons and global change. The woodrats' decline emphasizes its potential risk of extinction as global change continues to impact island ...

On the probability of extinction in a periodic environment
, 2014 For a certain class of multi-type branching processes in a continuous-time periodic environment, we show that the extinction probability is equal to (resp. less than) 1 if the basic reproduction number is less than (resp. bigger than) 1.

A roadmap to key traits of invasive Drosophilidae
Biological Reviews, EarlyView.ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.
