Dormancy stabilizes non-transitive competitive dynamics
José Chacón, Adrián González-Casanova, Imanol Nuñez +3
Competitive interactions can maintain diversity, yet coexistence is often fragile in well-mixed populations, where stochastic fluctuations can lead to extinction. This is the case…

The frequency process in a non-neutral two-type continuous-state branching process with competition and its genealogy
Imanol Nuñez, José Luis Pérez
We consider a population growth model given by a two-type continuous-state branching process with immigration and competition, introduced by Ma. We study the relative frequency of…

Alpha-stable branching and beta-Frequency processes, beyond the IID assumption
Adrián González Casanova, Imanol Nuñez, J. -L. Pérez
Birkner et al. obtained necessary and sufficient conditions for the frequency between two independent and identically distributed continuous-state branching processes time-changed…
